Question

A sprinter leaves the starting line and reaches a speed of 7 m/s in 3 seconds. What is his acceleration?

Answer 1

The answer is 2.33 m/s²

Step-by-step explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

`a = (v)/(t) \\`

v is the speed

t is the time taken

From the question we have

`a = (7)/(3) \\ = 2.33333333...`

We have the final answer as

2.33 m/s²

Hope this helps you
