  4. A truck carries a 2 ton stone-block on a level horizontal road. The coefficient of static and kinetic frictions between the stone-block and truck-bed are 0.4 and 0.2, respectively. When the truck accelerates at 2 m / s 2, how much friction (in N ) acts between the stone-block and the truck-bed? (g=10 m / s 2)

Q. A truck carries a $2$ ton stone-block on a level horizontal road. The coefficient of static and kinetic frictions between the stone-block and truck-bed are $0.4$ and $0.2$, respectively. When the truck accelerates at $2\, m / s ^{2}$, how much friction (in $N$ ) acts between the stone-block and the truck-bed? $\left(g=10\, m / s ^{2}\right)$Physics Question Image

Laws of Motion

Solution:

Maximum acceleration upto which no relative motion occur $=\mu g=4 \,m / s ^{2}$
So, no relative motion at $a=2 \,m / s ^{2}$
