[The value of g on the moon is ]
[The value of g on the moon is ]
A.
4.5 m
B.
9 m
AnswerC.
6 m
D.
7.5 m
Answer: Option B
Solution
Answer: Option B
Solution:
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.
