A sledge loaded with bricks has a total mass of 18.0 kg and is pulled at constant speed by a rope. The rope is inclined at 20.0Â° above the horizontal, and the sledge moves a distance of 20.0 m on a horizontal surface. The coefficient of kinetic friction between the sledge and surface is 0.550.
(a) What is the tension in the rope?
N
(b) How much work is done on the sledge by the rope?
J
(c) What is the increase in internal energy in the sledge and the surface due to friction?
J
