Average accelerations:

$\overline{){{\mathbf{a}}}_{\mathbf{a}\mathbf{v}\mathbf{g}}{\mathbf{=}}\frac{\mathbf{v}}{\mathbf{t}}}$

Newton's second law:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{m}}{\mathbf{a}}}$

A boxer’s fist and glove have a mass of m = 0.92 kg. The boxer’s fist can obtain a speed of v = 9.25 m/s in a time of t=0.23 s.

Part (a) Find the magnitude of the average acceleration aave in meters per square second, of the boxer’s fist.

Part (b) How much force did the boxer apply to his fist/glove, in newton?
