Applying Newton's Second Law, it is found that the force, in Newtons, is given by:
Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:
In this problem, mass of 50 kg, thus
Acceleration is <u>change in velocity divided by change in time</u>, that is:
In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:
Thus, the force is given by:
