Question

Acceleration due to gravity on a planet is 4.9m/s^2.If it is safe to jump from a height of 5m on the earth,the corresponding height on the planet will be

Answer 1

Answer:

10m

Explanation:

Let us consider the problem,

Let the initial velocity u=0

the final velocity will v

Acceleration due to gravity g=9.8m/s2

The vertical distance =5m

v²−u²=2gs

v²−0=2×9.8×5

=9.89m/s

On the planet so,

v²−0=2×4.9×h

Let the v=9.89m/s

then ,

98 / 2×4.9

=98 /9.8

=10m

Hence, the corresponding height on the planet  will be =10m.
