A persоn pushes а 47.5kg blоck оf ice аt аn angle 27.80 below the horizon across a lake as shown in the figure. Calculate the minimum force F (in N) he must exert to get the block moving. (Hint: Horizontal component of force = Static friction force) (The coefficient of static friction is 0.1 and the coefficient of kinetic friction is 0.03)
