A lift of mass 1000 kg

A body starts rolling down on an inclined plane, the top half of which is perfectly smooth and lower half is a lift of mass 1000 kg. A particle is projected upwards from the surface of the earth of radius R with a KE equal to half the minimum value needed for it to escape. To what height h does it rise above the surface of the earth. In figure shown below, a particle is travelling counter clockwise in circle of radius 10 m.

A coin is released inside a lift at a height of 2m from the floor of the lift. The height of the lift is 10 m. A mass of 10 kg is hung to a spring balance in lift. Then the tension in the cable of the lift is :. Then the tension in the cable of the lift is-.

This is an application of Newton's second law to the forces felt in an elevator. If you are accelerating upward you feel heavier, and if you are accelerating downward you feel lighter. If the elevator cable broke, you would feel weightless since both you and the elevator would be accelerating downward at the same rate. The phenomenon of " weightlessness " occurs when there is no force of support on your body. When your body is effectively in "free fall", accelerating downward at the acceleration of gravity, then you are not being supported. The sensation of apparent weight comes from the support that you feel from the floor, from a chair, etc. Different sensations of apparent weight can occur on an elevator since it is capable of zero or constant speed zero acceleration and can accelerate either upward or downward. If the elevator cable breaks then both you and the elevator are in free fall. The resultant experience of weightlessness might be exhilirating if it weren't for the anticipation of the quick stop at the bottom. Elevator Problem This is an application of Newton's second law to the forces felt in an elevator.

Power is a measure of the rate at which work is done - work done per unit time - and can be expressed as. Since work is the product of the applied force and the distance, power 1 can be modified to. Power is also a measure of the rate at which energy is converted from one form to another and can be expressed as. The work done by a 1 kW electric motor in 1 hour can be calculated by modifying 1 to. An electric winch is lifting a mass of kg 10m above the ground. The electric motor in the winch is W. The force weight acting on the mass due to the acceleration of gravity can be calculated as.
