Physics Math

A contestant in a winter games event pushes a 48.0 kg block of ice across a frozen lake with a rope over his shoulder at a 25 degree angle. 

The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03.

A.) Calculate the minimum force F (in N) he must exert to get the block moving.
 
B.) What is its acceleration (in m/s^2) once it starts to move, if that force is maintained?
