A 660kg car is moving with an initial speed of 10.0 m/s. A deer jumps into the road and the driver slams on his brakes, honks the cars horn, and says a prayer silently as he swears out loud. The car comes to a screeching halt after 4.00 seconds, just inched from the deer, which then nonchalantly proceeds to cross the road and get hit by a dump truck coming from the opposite direction. What average power is used to stop the car in watts
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.

Given data:
Mass (m) = 660 kg
Initial speed (v) = 10 m/s
Time (t) = 4.0 sec
Need to determine the average power is used to stop the car in watts.
