Questions
If the ring shown in the figure is restricted to move along the rod with speed 4m/s, the velocity of the mass ‘m’ is .......... m/s
detailed solution
Correct option is B
Velocity of ring is 4 m/s. The length of the string between the ring and the pulley is decreasing at a rate which is equal to the velocity (u) with which the block m is falling..: u = VR cos 600 = 4 x 1/2Talk to our academic expert!
