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 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. N (b) What is its acceleration (in m/s2 ) once it starts to move, if that force is maintained? m/s2
