Question:

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?

Answer:

The potential energy of a person will remain the same on the earth and on planet A
Potential energy = mgh
mg1h1 = mg2h2            (g1 = g, g2 = ½ g & h1 = 0.4 m)
Now, h2 = g1h1/g2 => g x 0.4 / (g/2) = 0.8 m.
