A lift is designed to carry a load of 4000kg through 10 floors of a building averaging 6m per floor in 10seconds. Calculate the forse power of the lift.

A lift is designed to carry a load of 4000 kg through 10 floors of a building, avarage 6m per floor, in 10s. Calculate the power of the lift.

An elevator in a building is designed to carry a load of 5000 kg throgh 10 floors . If height of each floor is 5 cm on an average and it takes 8 seconds to climb 10 floors , calculate the horse power of the lift .

A motor pump lifts 6 tonnes of water from a well of depth 25 m to the first floor of height 35 m from the ground floor in 20 minutes. The power of the pump (in kW) is [ g = 10 m s^(-2) ]

A lift, initially at rest on the ground, starts ascending with constant acceleration 8m//s^(2) After 0.5 seconds, a bolt falls off the floor of the lift. The velocity of the lift at the instant the bolt hits the ground is m/s .[Take g=10 m//s^(2) ]

9 persons enter a lift from ground floor of a building which stops in 10 floors (excluding ground floor), if it is known that persons will leave the lift in groups of 2,3, & 4 in different floors. In how many ways this can happen?

A motor pump lifts 6 tonnes of water from a height of 25 m to a height 35m from the ground floor in 20 seconds. The power of the pump (in kW) is [g = 10 ms^(-2)]
