Class 11PhysicsNewton's Laws of Motion and FrictionKinetic Friction and Motion on Rough Horizontal Surface
Difficult$A$ body of weight $64 \,N$ is pushed with just enough force to start it moving across a horizontal floor and the same force continues to act afterwards. If the coefficients of static and dynamic friction are $0.6$ and $0.4$ respectively, the acceleration of the body is (Acceleration due to gravity $= g$)
- A$\frac{g}{6.4}$
- B$0.64 g$
- C$\frac{g}{32}$
- D$0.2 \,g$
