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 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))

(Take C_(w)=4180 J kg^(-1) K^(-1)) A block of weight 5kg falls from a height of 5m into a bucket containing 10L of water. If all the mechanical energy of the block is used to heat water, find the rise in temperature of water. Take g= 10ms^(-2)

A man weighing 70kg carries a weight of 10kg on the top of a tower 100 m high. Calculate the work done by the man. (g = 10m//s^2)

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

An object of mass 12 kg is at a certain height above the ground. If the potential energy of the object is 480 J, find the height at which the object is with respect to the ground. Given. g=10 ms^(-2) .
