A sphere of mass m, is held between two smooth inclined walls. For `sin37^(@)=3//5`, the normal reactions of the wall (2) is equal to

A hemisphere of mass M and radius R rests on a smooth horizontal table. A vertical rod of mass m is held between two smooth guide walls supported on the sphere as shown. There is no friction between the rod and the sphere. A horizontal string tied to the sphere keeps the system at rest. (a) Find tension in the string. (b) Find the acceleration of the hemisphere immediately after the string is cut.

A ladder of mass 10kg is held at reat against a smooth wall on a rough ground as shown in figure. The normal reaction between the wall and the ladder is

A ladder of mass 10kg is held at reat against a smooth wall on a rough ground as shown in figure. The normal reaction between the wall and the ladder is

A man of mass 40kg is at rest between the walls as shown in the If '●' between the man and the walls is 0.8 find the normal reactions exerted by the walls on the man .

A sphere of mass m slides with velocity v on as frictionless surface towards a smooth inclined wall as shown in figure. If the collision with the wall is perfectly elastic find a. the impulse imparted by the wall on the sphere b the impulse imparted by the floor on the sphere.
