Question

4. A ball is dropped from a balloon going up at a speed of
7 m/s. If the balloon was at a height 60 m at the time
of dropping the ball, how long will the ball take in
reaching the ground ? using galelio trick . anyone give the answer I give brainliest answer​

Answer 1

Explanation:

So,after this it will start fallingdownwards due to the effect of gravity,so net displacement will be 60m ,as it willcome down by that distance through which it went upwards after releasing it. Here, s=60m,u=7ms (when returning to the point of release,it will gain the same velocity but direction will be reversed.)

HOPE IT HELPED YOU OUT.....

PLZ MARK AS BRAINLIST....

Answer 2

Answer:

A ball is dropped from a ballon going up at a speed of 7 m/s. If the balloon was at a height 60 m at the time of dropping the ball, how long will the ball take in reaching the ground? Therefore, the ball will take 4.2 sec, to reach the ground.
