A contestant in a winter games event pushes a 59.0 kg block of ice across a frozen lake as shown in the figure.
The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03.
(a)
Calculate the minimum force F (in N) he must exert to get the block moving.
(b)
What is its acceleration (in m/s2) once it starts to move, if that force is maintained?
