A Ping-Pong ball moving East at a speed of 4 m/s collides with a stationary bowling ball. The Ping-Pong ball bounces back to the West, and the bowling ball moves very slowly to the East.
Which object experiences the greater magnitude impulse during the collision? A) Neither; both experienced the same magnitude impulse.
B) It's impossible to tell since the velocities after the collision are unknown.
C) the bowling ball
D) the Ping-Pong ball
Question 2
A block lies on a smooth inclined plane tilted at an angle of 35 to the horizontal.
(a) Draw the free-body diagram for the block.
(b) Determine the block's acceleration as it slides down the inclined plane.
(c) If the block started from rest 8.5 m up the incline from its base, determine the block's speed when it reaches the bottom of the incline.
(d) How long did it take the block to reach the bottom of the inclined plane?
