Answer:
The altitude is 159.15 m.
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
[tex]E = 105\times\dfrac{40}{100}[/tex]
[tex]E=42\ Wh[/tex]
We need to calculate the energy in joules
[tex]E=42 Wh\times\dfrac{3600 J}{Wh}[/tex]
[tex]E=151200\ J[/tex]
We need to calculate the height
Using formula of energy
[tex]E = mgh[/tex]
[tex]h=\dfrac{E}{mg}[/tex]
[tex]h=\dfrac{151200}{950}[/tex]
[tex]h=159.15\ m[/tex]
Hence, The altitude is 159.15 m.
