A ladder AP of length `5m` inclined to a vertical wall is slipping over a horizontal surface with velocity of `2m//s`, when A is at distance `3m` from ground. What is the velocity of COM at this moment?

The end A of a ladder AP of length 5m, kept inclined to a vertical wall is slipping over a horizontal surface with velocity of 2m//s , when A is at a distance of 3m from the wall. Velocity of C.M. at this moment is

A disc of mass 2 kg is rolling on a horizontal surface without slipping with a velocity of 0.1 m/s. What is its rotational kinetic energy?

Rain is falling vertically downward with velocity 4m//s. A man is moving horizontally with velocity 3 m//s , the velocity of rain with respect to man is

A ladder of length 5 m is placed against a smooth wall as shown in figure. The coefficient or friction is mu between ladder and ground. What is the minimum value of mu , If the ladder is not to slip?

A link AB is moving in a vertical plane. At a certain instant when the link is inclined 60^(@) to the horizontal the point A is moving horizontaly at 3m//s , while B is moving in the vertical direction. What is the velocity of B ?

A rod AB of length 2L and mass m is lying on a horizontal frictionless surface. A particle of same mass m travelling along the surface hits the rod at distance (L)/(2) from COM with a velocity v_(0) in a direction perpendicular to rod and sticks to it. Angular velocity of rod just after collision is

A turck is moving on the ground with a velocity v=12m//s and a box is moving on the truck with respect to it with a velocity u=5m//s as shown in the figure. What is the velocity of the box with respect to the ground?

A ladder of length 50 m rests against a vertical wall, at a height of 30 m from the ground. Find the inclination of the ladder with the horizontal. Also find the distance between the foot of the ladder and the wall.
