Question 439: Gravitation

Question

The acceleration due to gravity on the planet A is 9 times the acceleration due to gravity on planet B. A man jumps to a height of 2 m on the surface of A. What is the height of jump by the same person on the planet B?

Accepted Answer

The velocity of the mass while reaching the surface of both the planets will be same.
i.e., $$\sqrt {2g'h'}  = \sqrt {2gh} $$
$$\sqrt {2 	imes g 	imes h'}  = \sqrt {2 	imes 9g 	imes 2} $$
$$ \Rightarrow 2h' = 36$$
$$ \Rightarrow h' = 18\,m$$

Answer

(2/9) m

Answer

18 m
