A contestant in a winter sporting event pushes a 49 kg block of ice at an angle 25∘ below the positive direction across a frozen lake, as shown in the figure. Assume the coefficients of static and kinetic friction are μs=0.1 and μk=0.03 Calculate the minimum force Fmin he must exert to get the block sliding across the ice in newtons. What is its acceleration in meters per second squared once it starts to move, if that minimum force is maintained?
