Determine the maximum acceleration of the train in which a box lying on its floor will remain stationary, given that the co-efficient of static friction between the box and the train’s floor is 0.15.

Text Solution

Verified by Experts

Due to static friction block will get acceleration
`:. Ma= f_(s)`
and `N = mg`
From equation ( 1)
`ma le mu_(s) mg`
`:. , a le mu_(s) g`
`a_(max) = mu_(s ) g`
`= 0.15 xx 10`
`:. , a_(max) = 1.5 ms^(-2)`
