Question

A 100-g ball rolls off a table and lands 2.0 m from the base of the table. A 200-g ball rolls off the same table with the same speed. It lands at distance?

Answer 1

Answer : The 200-g will land at the same distance (d) = 2.0 m

Since, Both the balls have same initial velocity and both the balls are dropped from same height.

So, time taken by both the balls to reach to the bottom will be same. (its independent of mass)

Now, Horizontal distance traveled by the ball = Initial velocity x time of flight.

Since, Initial velocities and time of flight of each ball is same for both the balls. So, Both the balls will hit the bottom ground at same distance (d) = 2.0 m
