A 70kg bicyclist, initially at rest at the top of a hill, coasts down the hill. During her ride she experiences a 40N drag. The distance and height of the hill are shown. What’s the loss

1 answer

To calculate the loss in potential energy of the bicyclist, we need to first determine the height of the hill. The height can be calculated using the equation:

Potential Energy = mass * gravitational acceleration * height

Potential Energy = 70kg * 9.8 m/s^2 * height

Given that the potential energy at the top of the hill is zero (as the cyclist is initially at rest), we can set the initial potential energy to zero:

0 = 70kg * 9.8 m/s^2 * height

Simplifying the equation:

height = 0

Therefore, the height of the hill is zero.

Since the height of the hill is zero, there is no loss in potential energy.
