3. Stations Go to the assigned station and attempt the problem given.
7 minutes each

4. Station 1
A football is kicked with an initial velocity of 25 m/s at an angle of 45 degrees with the horizontal.
Determine the total time of flight
The horizontal range of the ball
The peak height of the football

5. Station 2
A hunter sits on top of a stand in a tree 8 meters off the floor. He fires an arrow with a velocity of 21 m/s at 20 degrees above the horizontal and misses the deer.
What is the max height of the arrow?
How long is the arrow in the air?
What is the horizontal distance travelled?
