A70.0 kg sprinter starts a race with an acceleration of 1.60 m/s^2, what is the net external force (in n) on him? (enter the magnitude.) n

External force on him will be 112 N

Explanation:

We have given the mass of the sprinter m =70 kg

Acceleration of the sprinter

We have to find the net external force

According to second law of motion force = mass ×acceleration

Force is dependent on the mass and acceleration

So

So external force will be 112 N

d) the number of neutrons plus the number of protons

answer; equivalent to a one(1) horsepower motor;
