A lift is moving in upward direction with speed `20m//s` and having acceleration `5m//s^2` in downward direction. A bolt drops from the ceiling of lift at that moment. Just after the drop, the:

A

velocity of bolt with respect to ground is zero

B

velocity of bolt with respect to ground is 20 m/s in upwards direction

C

acceleration of bolt with respect to ground is `5m//s^(2)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
