Question

A 70-kg runner pushes off from the starting blocks with a force of 335N. what is her acceleration

Answer 1

We can use Newton's Second Law (F = ma) to solve for acceleration. First, solve it for 'a':

`a = (F)/(m)`

Now, plug in the numbers and solve for acceleration:

`a = (335)/(70) = 4.79`

So, your answer is: 4.79 m/s².
