A contestant in a winter games event pushes a 44.0 kg block of ice across a frozen lake as shown in the figure below. A person is pushing a block of ice to the right on the surface of a frozen lake. The person is applying force on the top-left corner of the block. The arrow representing the force vector F is shown to act diagonally downward from the shoulder of the person to the top left corner of the block. This arrow is at an angle of 25\deg below the horizontal from the person's shoulder level. 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.
