A contestant in a winter games event pulls a 43.0 kg block ofice across a frozen lake with a rope over his shoulder as shown inthe figure. The coefficient of static friction is 0.1 and thecoefficient of kinetic friction is 0.03.
(a) Calculate the minimum force F (in N) hemust exert to get the block moving.
(b) What is its acceleration (in m/s2) once it startsto move, if that force is maintained?
