A cart loaded with bricks has a total mass of 22.1 kg and is pulled at constant speed by a rope. The rope is inclined at 30.1 ◦ above the horizontal and the cart moves 23.9 m on a horizontal floor. The coefficient of kinetic friction between ground and cart is 0.3 . The acceleration of gravity is 9.8 m/s2 . What is the normal force exerted on the cart by the floor? Answer in units of N. b) How much work is done on the cart by the rope? Answer in units of kJ. c) Note: The energy change due to friction is a loss of energy. What is the energy change Wf due to fric- tion? Answer in units of kJ.

A box of mass ?=22.5 kg is pulled up a ramp that is inclined at an angle ?=17.0∘angle with respect to the horizontal. The coefficient of kinetic friction between the box and the ramp is ?k=0.305 , and the rope pulling the box is parallel to the ramp. If the box accelerates up the ramp at a rate of ?=2.49 m/s2, calculate the tension ?T in the rope. Use ?=9.81 m/s2 for the acceleration due to gravity. FT=_____N
