SUMMARY
The average force exerted by a shot-putter on a 7.5 kg shot can be estimated using Newton's second law (F=ma) and the work-energy theorem. Given that the shot is moved through a distance of 3.0 m and released with a speed of 11 m/s, the acceleration can be calculated using kinematic equations. Utilizing the work-energy theorem may provide a more efficient method for determining the force without extensive calculations involving kinematics.
