CLASSWORK: PROJECTICLES LAUNCHED HORIZONTALLY A rock is kicked horizontally off of a cliff at 20 m/s. If it traveled 1,220 m before it hit the ground, answer the following questions… a.What is the ball’s initial speed in the x and y direction? b.In which directions, if any is there acceleration? c.What is the final velocity right before the ball touches the ground in the x direction? d.How long was the rock in the air? e.What was the final velocity of the rock in the y direction right before it touches the ground? f.How high was the cliff?

NOTEBOOK ASSIGNMENT: THE CANNONBALL AND THE FORT A cannonball is launched at an angle of 45 degrees. The explosion of the gunpowder sends the cannonball flying at 180 m/s towards the fort which is 3290 m away and 10 m high. Does the cannonball successfully hit the fort? a. What is the ball’s initial speed in the x and y direction? b.In which directions, if any is there acceleration? c.If the fort was not there, how long would it take for the cannonball to hit the ground? d.If the fort was not there, how far would the cannonball travel e.How long would it take for the cannonball to collide with the wall? f.How high up would the cannonball hit the fort?

DIAGRAMMING A PHYSICAL SITUATION: PROJECTILES A football is thrown by a quarterback whose are arm is 2 m above the ground at an angle of 30 degrees. How far does the ball go before it lands?

GUIDED PRACTICE: THE CANNONBALL A cannonball is launched at an angle of 45 degrees. The explosion of the gunpowder sends the cannonball flying at 120 m/s. a.What is the cannonball’s initial speed in the x and y direction? b.In which directions, if any is there acceleration? c.How long would the cannonball take to reach its peak? d.How high is the cannonball’s peak? e.How long would the cannonball be in the air? f.How far does the cannonball travel? g.What is the final velocity of the cannonball right before it hits the ground? h.If the cannonball was tilted at a slightly lower or higher angle, what would happen to the range of the cannonball? If you can’t explain this, do the math to uncover the answer.

KAP#14 1.A movie director is shooting a scene that involves dropping a stunt dummy out of an airplane and into a swimming pool. The plane is 10.0 m above the ground, traveling at a velocity of 22.5 m/s in the positive x direction. The director wants to know where in the plane’s path the dummy should be dropped so that it will land in the pool. What is the dummy’s horizontal displacement? 2.In 1978, Geoff Capes of the UK won a competition for throwing 5 lb bricks; he threw one brick a distance of 44.0 m. Suppose the brick left capes’ hand at an angle of 45.0 degrees with respect to the horizontal. a.What was the initial speed of the brick? b.What was the maximum height reached by the brick? c. If Capes threw the brick straight up with the speed found in (a), what would be the maximum height the brick could achieve?

KAP#15 1.A ball flies at 2.0m/s a 30.0 degree angle to the horizontal. Find the ball’s maximum height, how long it will stay in the air, and its range. 1.In 1991, Doug Danger rode a motorcycle to jump a horizontal distance of 76.5 m. Find the maximum height of the jump if his angle with respect to the round at the beginning of the jump was 12.0°

KAP #16 1.The longest stuffed toy ever manufactured is a 420 m snake made by Norwegian children. Suppose a projectile is thrown horizontally from a height half as long as the snake and the projectile’s horizontal displacement is as long as the snake. What would be the projectile’s initial speed? 2.Measurements made in 1910 indicate that the common flea is an impressive jumper, given its size. Assume that a flea’s initial speed is 2.2 m/s, and that it leaps at an angle of 21 degrees with respect to the horizontal. If the jump lasts 0.16 s, what is the magnitude of the flea’s horizontal displacement? How high does the flea jump (in cm)?

#11 BREAK THE EGG LAB ACTIVITY Objective: Break the egg with the marble on the first try by rolling it off a table and through 3 rings. Take as many practice runs as you want, but you only get one shot once you want to break the egg. You will need to diagram the physics of this situation including identifying initial velocity, all accelerations occurring, the magnitude and direction of the velocity vectors below, the range of the projectile, the time of flight, height it drops from, etc. All this will need to be done and approved before you will be given a chance to break the egg. You will get one chance. If you break it you will get an extra credit stamp added to your notebook. v2v2 v1v1 vovo v3v3

HW 17 5.A projectile is launched from the top of a cliff above level ground. At launch the projectile is 35m above the base of the cliff and has an initial velocity of 50 meters per second at an angle of 37 degrees with the horizontal. Air resistance is negligible. Consider the following two cases and use g=10m/s 2. a.Calculate the total time from launch until the projectile hits the ground at point C. b.Calculate the horizontal distance R that the projectile travels before it hits the ground. c.Calculate the speed at at the highest point, at the height of launch of the projectile, and at the ground.

KAP #18 REVIEW x(m) t(s) The graph below represents a person moving. Describe what type of motion is present during each interval, and create the velocity vs. time graph and the acceleration vs time graph. 2. A car accelerates over an unknown time interval. If the car was initially at rest, reached a maximum velocity of 90 km/hr and accelerated over a distance of 3000 m, how long did it accelerate and what was the magnitude of its acceleration? 3. A piano is dropped from 2000 m from the sky onto a building 10 m off the ground. Assuming no air resistance, how long would it take to reach the ground and how fast would it be going right before it hit the ground. 4. An airplane is moving at 250 m/s. when a piano drops from the back of the airplane. If the airplane is 2 km above the ground, how long is it falling? How far (horizontally) from its release point will it land?
