Question

A ball rolls horizontally with an initial velocity of 3 m/s off a table. The ball hits the floor 2.9 m away. What is the time it takes for the ball to hit the floor?

a) 0.97 seconds
b) 0.98 seconds
c) 0.99 seconds
d) 1.00 seconds

Answer 1

The time it takes for the ball to hit the floor is 0.97 seconds.

Step-by-step explanation:

To find the time it takes for the ball to hit the floor, we can use the equation for horizontal motion:

distance = velocity x time

In this case, the distance is 2.9 m and the initial velocity is 3 m/s.

Rearranging the equation, we have:

time = distance / velocity

Plugging in the given values, we get:

time = 2.9 m / 3 m/s

time = 0.97 seconds

Therefore, the answer is 0.97 seconds (option a).
