Class 11PhysicsNewton's Laws of Motion and FrictionKinetic Friction and Motion on Rough Horizontal Surface
MediumConsider a block and trolley system as shown in the figure. If the coefficient of kinetic friction between the trolley and the surface is $0.04$,the acceleration of the system in $m/s^2$ is (Consider that the string is massless and unstretchable and the pulley is also massless and frictionless):
- A$3$
- B$4$
- C$2$
- D$1.2$
