What height can he jump on the moon, if a person jumps 1.5 meters hight on the earth?
[The value of g on the moon is $${\frac{1}{6}^{th}}$$]
A. 4.5 m
B. 9 m
C. 6 m
D. 7.5 m
Answer: Option B
Solution (By Examveda Team)
On the moon, the gravitational acceleration (gmoon) is 1/6th that of the Earth.The height a person can jump is inversely proportional to the gravitational acceleration.
So, if a person can jump 1.5 meters on Earth, then on the Moon, the jump height will be:
Height on Moon = Height on Earth × (gearth / gmoon)
= 1.5 × 6 = 9 meters
Therefore, a person who jumps 1.5 m high on Earth can jump 9 m high on the Moon.
