When a shot-putter exerts a net force of 140 N on a shot, the shot has an acceleration of 19 m/s 2 . What is the mass of the shot?

Answer 1

This is a poorly worded question. A shot-putter exerts a force. The net force is the result of the force exerted combined vectorially with the gravitational force.

Since they are saying that you are given the net force on the object, just use Newton's 2nd law solved for m:

F_Net/a = m

You will get kg.
