A body is dropped from a balloon meving up wigh a velocity of `4 m s^(-2) ` when the balloon is at a height of `12.5` m from the ground.
The distance of separation between of separation between the body and the balloon after `5` is.

Options

A. `122.5 m`
B. `100.5 m`
C. `132.5 m`
D. `112.5 m`

Answer

A

Explanation

The distance travelled by the balloon in `5 s` upwards in `4 xx 5 =20 m`.
Distance of separation `=20+ 102.5 =122.5 m`.
