Question

a balloon starts rising from rest with acceleration 2 metre per second square from the ground after 4 seconds a stone is released from balloon find the displacement covered by stone from position where from stone is released.(take g =10 m per second square)​

Answer 1

Answer:

16 m

Explanation:

We are given that

Acceleration of  stone=$2 m/s^2$

Time=$t=4 s$

$g=10 m/s^2$

Initial velocity=$v_0=0$

We have to find the displacement covered by stone from position where from stone is released.

$S=ut+\frac{1}{2}at^2$

Substitute the values then we get

$S=\frac{1}{2}(2)(4)^2=16 m$

Therefore, the displacement covered by stone=16 m
