& contestant in a winter games event pushes a 35.0 kg block of ice across a frozen lake as shown in the figure below. The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03. (For each answer, enter a number.) fa) Calculate the minimum force F (in N} he must exert to get the block moving. 36.18 % N (b} What is its acceleration {in m;'sz} once it starts to move, if that force is maintained? x ms
