Instantaneous Power

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.

Question

A 2.11 kg cart moving along a horizontal track in the positive x direction has a changing force exerted on it. The force exerted on the cart is plotted in the graph shown. In the plot, F_max has a value of 5.95 Newtons. Note that the friction between the cart and track is negligible.

a.-Calculate the work done on the cart when it has reached a displacement of 21.3 cm along the track.

b.- If the cart starts from rest, calculate how fast the cart is going when it has reached a displacement of 21.3 cm along the track.
