A boy having a mass equal to 40 kilograms is standing in an elevator. The force felt by the feet of the boy will be greatest when the elevator
`(g=9.8"metres"//sec^(2))`

A student whose weight is 50 kg is standing in an elevator. The force felt by the feet of the student will be maximum, when the lift is

A man of mass 80 kg stands in an elevator. Calculate his apparent weight when, (iv) the elevator cable breaks (g = 10 m//s^2)

What is the weight of a 1 kilogram mass on the earth? (g = 9 .8 m//s^2).

A man of mass m is standing in an elevator moving downward with an acceleration (g)/(4) . The force exerted by the bottom surface of the elevator on the man will be

A man of mass m is standing in an elevator moving downward with an acceleration (g)/(4) . The force exerted by the bottom surface of the elevator on the man will be

A man of mass 50 kg is standing in an elevator. If elevator is moving up with an acceleration (g)/(3) then work done by normal reaction of elevator floor on man when elevator moves by a distance 12 m is (g=10 m//s^(2)) :-

A boy having a mass of 40kg stands at one end A of a boat of length 2m at rest. The boy walks to the other end B of the boat and stops. What is the distance moved by the boat? Friciton exists between the feet of the boy and the surface of the boat. But the friction between the boat and the water surface may be neglected. Mass of the boat is 15kg .
