a cart loaded with bricks has a total mass of 17.2 kg and is pulled at constant speed by a rope. the rope is inclined at 20.2 degrees above the horizontal and the cart moves 19.2 m on a horizontal floor. the coeffiecient of kinetic friction between the ground and the cart is .8. The acceleration of gravity is 9.8 m/s^2.
what is the normal force exerted on the cart by the floor?
how much work is done on the cart by the rope?
(note the energy change due to friction is a loss of energy) what is the energy change due to friction?
=basically i don;t even know where to start :(
any help is appreciated!
Thanks
