Question 2 Where in a projectile’s path will it have the maximum velocity?

Question 3 At what angle should a projectile be launched to have maximum range?

Question 4 Explain the difference between an object thrown straight up and a projectile at their maximum points.

Question 5 A rock fell off a cliff and is traveling 30 m/s, what is the rock’s acceleration?

Question 6 If a plane is heading north at 100 km/h and encounters a headwind of 15 km/h, what is the resulting velocity?

Question 7 If a projectile is launched upward at a speed of 20 m/s, how long will the object be in the air for?
