1. Ignoring details associated with friction, extra forces exerted by arm and leg muscles, and other factors, we can consider a pole vault as the conversion of an athlete’s running kinetic energy to gravitational potential energy. If an athlete is to lift his body 5m during a vault, what speed must he have when he plants his pole?

 
 
 
 

2. A particle of mass m at rest is acted upon by a force P for time t. Its kinetic energy after time t is :
