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 height is 12m and distance is 65m. What’s the loss J
The loss J refers to the loss of potential energy as the cyclist descends the hill.
The potential energy loss can be calculated using the formula:
Potential energy loss (J) = mgh,
where m is the mass of the cyclist (70 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height (12 m).
Plugging in the values, we get:
Potential energy loss (J) = 70 kg * 9.8 m/s^2 * 12 m
= 8,274 J
Therefore, the loss J, or the potential energy loss, is 8,274 J.
