Question

A ball is dropped from the top of a 91-m-high building. What speed does the ball have in falling 3.2 s?

Answer 1

The speed of the ball is 28.4m/s.

Step-by-step explanation:

Given that the formula of speed is Speed = Distance/Time. So you have to substitute the values into the formula :

`speed = distance / time`

Let distance = 91m,

Let time = 3.2s,

`speed = 91 / 3.2`

`speed = 28.4 \: metrepersecond`
