A contestant in a winter games event pulls a 38.0 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) 250 ( b ) Figure 4.29 (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
