Question

A food packet dropped from a helicopter reaches the ground in 5s. If the velocity with which it hits the ground is 60m/s. what is the acceleration?​

Answer 1

Correct option is

C

18 m/s

The food packet has an initial velocity of 2 m/s in upward direction, therefore

v=−u+gt or

v=−2+10×2=18 m/s

Answer 2

Answer:

The food packet has an initial velocity of 2 m/s in upward direction, therefore

v=−u+gt or

v=−2+10×2=18 m/s
