A bag is gently dropped on a conveyor belt moving at a speed of $2\,m / s$. The coefficient of friction between the conveyor belt and bag is $0.4$ Initially, the bag slips on the belt before it stops due to friction. The distance travelled by the bag on the belt during slipping motion is $.....m$ [Take $g=10\,m / s ^{-2}$ ]

A

$2$

B

$0.5$

C

$3.2$

D

$0.8$

(JEE MAIN-2022)

Solution

In frame of belt

$a=\mu g=4 m / s ^{2}, v =2 m / s , u =0$

$v ^{2}= u ^{2}+2 as$

$s =0.5\,m$
