A 51-kg packing crate is pulled with constant speed across a rough floor with a rope that is at an angle of 34.0° above the horizontal. If the tension in the rope is 115 N, how much work is done on the crate to move it 9.7 m
Force (component along direction of motion) x distance
115 N * cos34 * 9.7 m = ___ Joules
