The height (in meters) from its position of rest of a spring as it bounces up and down can be modelled by the function $h\left(t\right)=2\sin \left(60°t\right)+1$, where $t$ is measured in seconds. Determine the function if the amplitude is same as the maximum height from its position at rest.

When you ride a Ferris wheel, your vertical height above the ground changes. The relationship between your height above the ground and the time for a complete revolution of the wheel can be modelled with the sinusoidal graph given below. State the height at which you board the Ferris wheel.
