An ball rolls off a very tall table at a constant speed of 2 m/s. The ball is in the air for 5 seconds. Between t = 4 seconds and t = 5 seconds, how much horizontal distance does the ball cover?

Back

2 meters

Answer explanation

Horizontal velocity is constant for a projectile.

If the ball starts with a horizontal velocity of 2 m/s, it will continue to have a horizontal velocity of 2 m/s for its entire trajectory. This means it will travel 2 horizontal meters in each second.
