According to this equation f equals ma how much force is needed to accelerate a 70 kg runner at 5 m/s^2.

ANSWER
The required force is


EXPLANATION

The force needed to accelerate a 70kg runner at is the product of the mass of the runner in kilograms and the acceleration in meters per seconds square.

The equation is given by,



where


and



This implies that,



We multiply to get,



Therefore the needed force is 350 Newtons.
