You and your lab partner devise a clever experiment to measure the force applied to a ball when it is thrown. You throw a 200-{g} ball vertically upward. A high-speed video image of the throw indicates your hand pushed on the ball for 0.32 {\rm s}. The ball rises to a maximum height of 7.23 {\rm m} above your hand.(adsbygoogle = window.adsbygoogle || []).push({});

Calculate the force applied.

I tried.

Y = 1/2at^2

so

7.23m = 1/2(9.81m/s/s)(t^2)

Solved for t = 1.2 seconds...

Now I know F = ma

so is it simply F = 0.2kg*9.81m/s/s?

Im not sure
