A contestant in a winter games event pulls a 35.0 kg block of ice across a frozen lake with a rope over his shoulder as shown in Figure 4.29(b). The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03.
25°
(a) Calculate the minimum force F he must exert to get the block moving.
_________N
(b) What is its acceleration once it starts to move, if that force is maintained?
_________m/s2
