Question

A foodpacket dropped from a helicopter reaches the ground is 5s.If the velocity with which it hits the ground is 50m/s.what is the acceleration

Answer 1

Explanation:

since here it's not given the velocity of the helicopter, consider it to be static at the sky

therefor

initial velocity of the food packet =u=0m/s

final velocity =50m/s

acceleration =a =?

time taken by the foodpacket to reach the ground =t =5s

according to formula

v=u+at

50=0+(a×5)

a=10m/s²
