A 10.0 kg block is at rest on a frictionless horizontal table. A student applies a constant 40.0 N force at an angle of 60.0 degrees, as shown in the figure below. The block remains in contact with the table as it is dragged along.
a) How far does the block move in 5.00 seconds? b) How much work is done by the applied force? c) What is the speed of the block after 5.00 seconds? d) What is the kinetic energy of the block after moving this distance? e) Compare the answers for b and d. If the answers are the same, explain. If they differ,
explain why they differ.
