`T sin^(●) =ma_(0) + mg sin^(●)------(1)`
`T cos^(●) =mg cos^(●)------(2)`
`(①)/(②) rArr tan^(●) = (a_(0)+g sin^(●))/(g cos^(●))`

A pendulum of mass m hangs from a support fixed to a trolley which is moving up to the inclined plane with uniform acceleration 'a'. The angle which the string makes with vertical in equilibrium is

A pendulum has a ball of mass m attached to the stringa and is suspended from the roof of a trolley. If the trolley rolls upwards with acceleration a, then what is the angle made by the string with the inclined plane? (Given that, a=5m//s^(2), g=10m//s^(2) and the angle of inclination of the plane is 30^(@) )

A (trolley + child) of total mass 200 kg is moving with a uniform speed of 36 km/h on a frictionless track. The child of mass 20 kg starts running on the trolley from one end to the other (10 m away) with a speed of 10 ms^(–1) relative to the trolley in the direction of the trolley's motion and jumps out of the trolley with the same relative velocity. What is the final speed of the trolley? How much has the trolley moved from the time the child begins to run?

A pendulum bob is hanging from the roof of an elevator with the help of a light string. When the elevator moves up with uniform acceleration 'a' the tension in the string is T_(1) . When the elevator moves down with the same acceleration, the tension in the string is T_(2) . If the elevator were stationary, the tension in the string would be

A block B is m kept on an inclined plane. Anotherblock A is inserted in a slot in the block B though a light string. One end of the string is fixed to a support and other end of the string is attached to A. All the surfaces are smooth. Masses of A and B are same. The acceleration of block B is found to be 4//n .Find value of n.
