Question

what force is required to accelerate a 115kg linebacker at a rate of 3.5m/s2

Answer 1

Hi Ashley;

A unit of force is a Newton.

A Newton is kg m/s², the requirement to move one kilogram, one meter, at an acceleration rate per-second for every second.

F=ma

F=(115 kg)(3.5 m/s²)

F=402.5 Newtons

 

 

Answer 2

This is a good use of the F=ma or Force is the product of mass times acceleration. In this case m=115 and a=3.5 so F=402.5 N (kg m/s.)
