The weight of a person on a planet A is about half that on the earth. He can jump upto \(0.4\ m\) height on the surface of the earth. How high he can jump on the planet A?

The formula to calculate the Potential energy (\(P.E\)) is,

\(P.E\ =\ m \times g \times h\)
\(P.E\ =\ m \times g\ +\ h\)
\(P.E\ =\ m \times \frac{g}{h}\)
\(P.E\ =\ m \times g\)

Weight is calculated by:

\(Weight\ =\ \frac{Mass}{Gravity}\)
\(Weight\ =\ Mass \times Gravity\)

The person can jump on the planet A up to height of \(m\)
