A block of mass m is moved over a distance d. An applied force F is directed perpendicularly to the block’s displacement. How much work is done on the block by the force F?

A light plane travels a distance of 150 m along a runway before takeoff. Find the work done by the plane engine if it is applying a force of 13500 N. ( W =Fd )

A motorcycle has 10 J of kinetic energy. If its velocity is doubled, how much kinetic energy does it now possess?

The elastic force as a function of displacement presented by the graph. How much elastic potential energy is stored in the spring when it is stretched by 10 cm? ( Science measures displacement in meters. ) A_Δ =1/2bh

A horizontal spring is used to launch a 2.0 kg ball. The spring is compressed by 0.25 m and has a spring constant k of 1,000 N/m. What is the maximum speed of the ball? This is a conservation of energy problem (EPE = KE )
