Hey if anyone could help me work through a couple of problems that would be great!(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

It is not uncommon during the service of a professional tennis player for the racquet to exert an everage force of 150.0N on the ball. If the ball has a mass of 0.060kg and is in contact with the strings of the racquet for 0.030s what is the kinetic energy of the ball as it leaves the racquet? Assume the ball starts from rest

2. Relevant equations

Ek=1/2mv^2

3. The attempt at a solution

I'm not sure really where to start here....
