A small steel ball of mass 0.29 kg is fired at a speed 17.5 m/s and runs into some soft putty, penetrating a distance of 4 cm. What is the average force experienced by the ball from the putty?

1 answer

Favg=((0.5)mv^2)/(d)

=(0.5*0.29*17.5^2)/(0.04)
don't forget to convert units to match, in this case the distance into meters
