Question

Three balls leave the edge of a table at the same time. Ball A rolls off the table with an initial horizontal velocity. Ball B is launched at an angle and has both an initial horizontal and vertical velocity. Ball C is dropped from rest, and has no initial velocity.

a) Explain which one(s) hit the ground first.

b) Explain which one(s) hit the ground last

Answer 1

Step-by-step explanation:

Balls A and C have the same initial vertical velocity of zero. Therefore, they land at the same time.

Ball B has a positive initial vertical velocity, so it hits the ground last.
