Question

4. Each croquet ball in a set has a mass of 0.50 kg. The green ball, traveling at 12.0 m/s,

strikes the blue ball, which is at rest. Assuming that the balls slide on a frictionless
surface and all collisions are head-on, find the final speed of the blue ball in each of the
following situations:
a. the green ball stops moving after is strikes the blue ball. (12 m/s)
b. the green ball continues moving after the collision at 2.4 m/s in the same
direction. (9.6 m/s)
c. the green ball continues moving after the collision at 0.30 m/s in the same
direction. (11.7 m/s)

Answer 1

C

Step-by-step explanation:

I think the answer is C because there is no friction to stop the ball and the ball will collide together which will increase the speed because the greater the mass the greater the velocity.
