engineering recuitment GATE CE 2023-24 Test Series Engineering Mechanics Equilibrium and Friction Friction
A wooden block of mass 10 kg is at rest initially as shown in the figure. A linearly time varying force is applied. The static and kinematic coefficients of friction are 0.6 and 0.4, respectively. The velocity of the block at t = 4s in m/s will be (take g = 10 m/s2):
