Question

The mass of a bike and cyclist is 75.0 kg. The rider starts at rest at a height of Om. She speeds up to 6.00 m/s. What is the potential energy of the bike?

Answer 1

The mass of the bike along with the cyclist is m = 75 kg.

The rider starts from rest and the height is h = 0 m.

Also, acceleration due to gravity is g = 9.8 m/s^2

The formula to find potential energy is

$P\mathrm{}E\text{. = mgh}$

Substituting the values, the potential energy will be

$\begin{gathered} P\mathrm{}E\text{. = 75}\times9.8\times0 \\ =0\text{ J} \end{gathered}$
