Question

4 balloons are ascending with uniform velocities 3m/s , 2m/s , 1m/s and 4m/a at the ​

Answer 1

CORRECT QUESTION:

Four balloons are ascending with uniform

velocities 3m/s, 2m/s, 1 m/s and 4m/s. At the

instant when all balloons are at the same height,

a cricket ball is released from each balloon. The

ball that will strike the ground first is from the

balloon ascending with what speed??

$\huge\b{ANSWER:}}$

4m/s.

EXPLANATION:

Given:

• Four balloons are ascending with velocities 3 m/s, 2 m/s, 1 m/s and 4 m/s

• A cricket ball is dropped from each balloon

To find :  

• The ball which will strike the ground first .

When a balloon is ascending and an object is dropped the Initial velocity of the object will be same as the velocity of the ascending speed if the balloon

The height for all the three balloons is same .

So the balloon with speed of 4 m/s will have highest speed transmission to the cricket ball .

So, as 4 m/s balloon will have highest Initial velocity, it will reach the ground first.
