Kinematics Question 245

Question: A packet it’s dropped from a balloon Which is going upwards with the velocity 12 m/s, the velocity of the packet after 2 seconds will be [Pb PMT 2004]

Options:

A) ?12 m/s

B) 12 m/s

C) ?7.6 m/s

D) 7.6 m/s

Show Answer

Answer:

Correct Answer: C

Solution:

When packet it’s released from the balloon, it acquires the velocity of balloon of value 12 m/s. Hence velocity of packet after 2 sec, will be $ v=u+gt $

$ =12-9.8\times 2 $ = ? 7.6 m/s.
