Problem 10: A contestant in a winter sporting event pulls a 42 kg block of ice in the positive horizontal direction with a rope over his shoulders across a frozen lake as shown in the figure. Assume the coefficients of static and kinetic friction are u=0.1 and u=0.03. 25° Part (a) Calculate the minimum force F he must exert to get the block sliding in newtons. Fmin =
