A contestant in a winter games event pushes a 50.0 kg block of ice across a frozen lake as shown in the figure below. 25° b The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03. (For each answer, enter a number.) (a) Calculate the minimum force F (in N) he must exert to get the block moving. 586 XN (b) What is its acceleration (in m/s2) once it starts to move, if that force is maintained? x m/s² 9.89
