A contestant in a winter games event pulls a 39.0 kg block of ice across a frozen lake with a rope over his shoulder as shown in the figure

The figure shows 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/s2) once it starts to move, if that force is maintained?
