On a stationary block of mass `2kg` a horizontal forces F starts acting at `t = 0` whose veriation with time is shown in figure .The coefficient of friction between the block and ground is `0.5` New answer the following question

Find the velocity of the at `t = 12s`

A

`20 ms^(-1)`

B

`-12 ms^(-1)`

C

`+6 ms^(-1)`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
d
From the above discassion, clearly , velocity is zero at ` t = 12 s`
