Question

If a man can jump 6m high on the surface of the earth, how high can he jump on the surface of the moon ?

Answer 1

Answer:

36 m

Explanation:

Because moon's gravity is one sixth of the earth

Answer 2

Answer:

Explanation:

so we see at the top most point the velocity the boy is zero and the earths pull is acting downwards,

Given gm/ge=1/6,

⇒ge=6gm,

so using,

v²=u²-2gs      where g = acceleration due to gravity

                                      s = total height ,

so,

0 = u² - 2gs   ,

⇒S=u²/6ge,

⇒6=u²/6ge,

putting ge=6gm,

⇒6=u²/36 gm,

⇒36=u²/6 gm,

so the boy can jump a height of 36 m on moon's surface.

Or in simple method:

take the value of on earth as x,

value of g on moon=6x,

x=6,

So the height on moon=6x=6(6),

36 m is the height.

Hope it helps.
