Question

An object is dropped from a balloon rising up with a velocity 2 ms-1. Find the velocity of the object after 2 seconds
of its release. (take g = 10 ms-2)
(1) 9 ms-1
(2) 18 ms
(3) 27 ms-1
(4) 36 ms-1​

Answer 1

Answer:

Here, u = 2 ms-1, t = 2s, a = 10 ms-2

Using

v = u + at

We get

v = 2 + 10 × 2

=> v = 22 ms-1

Thus, velocity of the object after 2 seconds will be 22 ms-1
