Question

An electric scooter has a battery capable of supplying 105 Wh of energy. If friction forces and other losses account for 60.0% of the energy usage, what altitude change can a rider achieve when driving in hilly terrain, if the rider and scooter have a combined weight of 950 N?

Answer 1

The altitude is 159.15 m.

Step-by-step explanation:

Given that,

60% Energy lost due to the friction and other losses, which means we have only 40% Energy is available to use, so

Energy = 405 of 105 Wh

Energy losses is

`E = 105*(40)/(100)`

`E=42\ Wh`

We need to calculate the energy in joules

`E=42 Wh*(3600 J)/(Wh)`

`E=151200\ J`

We need to calculate the height

Using formula of energy

`E = mgh`

`h=(E)/(mg)`

`h=(151200)/(950)`

`h=159.15\ m`

Hence, The altitude is 159.15 m.
