Question

A ball rolls off at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land?

Answer 1

1.20 m

Step-by-step explanation:

Answer 2

If we ignore air resistance, then the horizontal speed
of the ball doesn't change after it rolls off the edge. So

(distance) = (speed) x (time)

= (3 m/s) x (0.4 sec) = 1.2 meters .
