Wile E Coyote (below) has a mass of 12.5 kg and is on a hill with a height of 55 m above a valley. He wants to reach Road Runner, who is on a hill with a height of 100 m on the other side of the valley, by using an ACME rocket attached to some wheels. Assume that friction is negligible. a) What is the potential energy of Wile E Coyote when he is on the 55-m ill and what would be his potential energy if he reaches the 100-m hill? b) What is the minimum initial speed (provided by the rocket) that would allow Wile E Coyote to reach the other side? c) If the initial speed of Wile E Coyote is 25 m/s, what is his speed at the bottom of the valley? 100m 55m
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.
