A cart is moving to the right with a constant speed of 20 m/s. A box of mass 80 kg moves with the cart without slipping. The coefficient of static friction between the box and the cart is 0.3 and the coefficient of kinetic friction between the box and cart is 0.15.

a) find the direction and magnitude of the force of friction that the box exerts on the moving cart
b) what is the net force acting on the cart?
c) what is the normal force exerted on the 80 kg object?
d) what is the force of friction acting on the 80 kg box?
for b) and find the maximum acceleration of the block?
