6. At t = 0 a paintball is shot out of a paintball gun horizontally off a 1000 m tall cliff. At the same time, a paintball is released from rest (dropped from the same height). Ignoring air resistance, which paintball strikes the ground with a higher speed? A) The paintball shot from the gun. B) The paintball released from rest. C) Both paintballs hit the ground with same speed. D) The answer depends on the initial velocity of the paintball fired from the paintball gun. 7. A football is aimed at a target on the wall a distance L away from the throwing position, from which the football is launched horizontally. Because of gravity, the bullet strikes the wall a distance Ay below the mark as suggested in the figure. If the distance L was half as large and the football had four times initial velocity, how would Ay be affected? A) Ay will double. B) Ay will be half as large. C) Ay will be four times larger. D) Ay will be one fourth as large. 8. A ball is kicked from the ground an initial speed v at an angle g above the horizontal. Which of the following best describes the magnitudes of the velocity and acceleration of the ball when it reaches the highest point of its trajectory? A) Velocity: 0 Acceleration: g B) Velocity: vcose Acceleration: g C) Velocity: v Acceleration: 0 D) Velocity: 0 Acceleration: 0 Part 2: Free Response.
