a man is pulling rope at a contant speed of 10m/s with a power of 500 joules/s. the change in KE of bolck is 100 joule /s. find the mass of bolck. block is hanging with a massless rope, over a pulley. other end of rop is being pulled with an angle of 60 degrees being made between ropes around pulley.
