Question

A 78 kg runner exerts a force of 69 N. What is the acceleration of the runner?(use the formula a=F/m)

Answer 1

The answer is 0.88 m/s²

Explanation:

To find the acceleration given the mass and force we use the formula

`a = (f)/(m) \\`

where

a is the acceleration

m is the mass

F is the force

From the question

m = 78 kg

F = 69 N

We have

`a = (69)/(78) = (23)/(26) \\ = 0.8846153...`

We have the final answer as

0.88 m/s²

Hope this helps you
