Question

A helicopter is at the height of 24 m when it drops a food packet. If velocity of helicopter during ascending is 2 ms -1, find the velocity of the packet. Take g 10 m/s2​

Answer 1

Answer:

A helicopter is ascending with a velocity of 2 m/s at a height of 24 m when it drops a mail packet. The packet contains material, which can be damaged if it hits ground with velocity of magnitude greater than 72 km / h. Was the packet damaged? Explain your answer.

(Take g = 10 m/s2)

Ans

As the packet reaches the ground with a velocity (22 m/s) greate

Ans

As the packet reaches the ground with a velocity (22 m/s) greater than the safe velocity of 20 m/s, so it is damaged.
