Question

If coefficient of kinetic friction is ${\mu }_k=0.04$ between the surface and trolley then the acceleration of trolley-block system as shown in diagram will be$(g=10m/s^2)$

• A. $0.956m/s^2$
• B. 0.33$m/s^2$
• C. 0.75$m/s^2$
• D. 0.66$m/s^2$

Answer 1

The correct option is A $0.956m/s^2$

If the coefficient of kinetic friction between the trolley and the surface is $\mathrm{0.04.}$

The acceleration of the block and trolley system as shown would be $0.956m/s^2$

Hence,

option $\left(A\right)$ is correct answer.
