A crate moves 10 m to the right on a horizontal surface as a woman pulls on it with a 10 N force as shown. Rank the situations shown below according to the work done by her force, least to greatest. A 10 N 10 N 10 N 1 3 O 1.1,2,3 O 2.2,1,3 O 3.2,3,1 O 4.1,3,2 O 5.3,2,1

A 1380 kg block is being pulled across the floor by a rope which is wrapped around a motorized winch. The coefficient of kinetic friction between the block and the floor is 0.41, and the block moves at a constant speed of 1.34 m/s.What is the power output of the motor, in Watts (W)?Calculate the total work done by the winch if the box moves a total of 4.50 meters. Give your answer in Joules (J).

Two electric pumps are being used to pump water to a cistern at the top of a 50 meter hill. A meter is used to measure the electrical energy in kWh consumed by both pumps over a six-hour period. Both pumps consume the same kWh of electrical energy over the pumping period. If we know that pump #1 has an efficiency of 40% and pump #2 has an efficiency of 80%, what can we say about the volume of water moved by each pump? Assume both pumps use the same piping system, so hydraulic frictional losses are the same for both pumps. pump #1 moved twice as much water as pump #2 pump #2 moved twice as much water as pump #1 both pumps moved the same amount of water
