A man of weight 50kg carries an object to a height of 20m in a time of 10s .The power used by the man in this process is 2000W then find the weight of the object carried by the man take `g=10ms^(-2)`

A man of weight 50 kg carries an object to a height of 20m in a time of 10 sec. The power used by the man in this process is 2000W, then find the weight of the object carried by the man [assume g = 10 ms^(-2) ]

An weight lifter an weight of 300 kg at 2m height from floor at 3 s time.The power exerted by the man is:

A man carries a load of 50 kg to a height of 40 m is 25s. If the power of the man is 1568 W, the mass of the man is

A man carries a load of 50 kg through a height of 40 m in 25 seconds. If the power of the man is 1568 W , his mass is

A crane lifts a mass of 100 kg to a height of 10m in 20s . The power of the crane is (Take g = 10 ms^(-2))
