Question

A system is shown in the figure. A man a standing on the block is pulling the rope. Velocity of the point of string in contact with the hand of the man is $2m/s$ downwards. The velocity of the block will be: [Assume that the block does not rotate]

• A. $3m/s$
• B. $2m/s$
• C. $\frac{1}{2}m/s$
• D. $1m/s$

Answer 1

The correct option is B $2m/s$

A system is shown in the figure. A man a standing on the block is pulling the rope. Velocity of the point of string in contact with the hand of the man is 2m/s downwards. As the single rope is attached to the block from between the pulley and man's hand hence speed of block will be 2m/s upwards
