A 400.0 KG mass experiences a horizontal push force of +720N And friction force of 320N

A) assuming the mass is initially moving at 5.0 m/s far will it travel in 6.0 s?
B) how much work does the 720.0 newton force do over the distance determine in part a?
C) calculate the power of the 720.0 N force using the result from part b and the given amount of time
