Inputs and outputs of brakes on a bike

The input is what you put into a bicycle when you ride it. It is the pedalling force and the pedalling speed. In the process box in the middle is the bicycle. The chain drive of the bicycle changes the input pedalling force and pedalling speed into an output.

Explanation:

50 inches should be the resultant vector

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
