A block is tied to one end of a light string of length 1 whose other end is fixed to a rigid support. The block is given a speed of `sqrt(7gl//2)` from the lowermost position. Find the height and speed at which the block leaves the circle. Also find the maximum height to which it rises finally.

A small block of mass m is attached to free end of a spring of force cosntant k , whose other end is fixed to a rigid support . The block is lying on a frictionless horizontal plane and it starts movi0ng away from fixed end of the spring a\t t= 0 with intial velocity u When the speed of the block is 0.6mu it collides with a fixed heavy mass elastically. After the collision with a fixed heavy mass elastically . Aftere the collision the time at which the block passes through its equilibrium position for the first time is close to

A stone is tied to one end of a light inexensible string of length l and made to roate on a vertical circle keeping other end of the spring at the centre. If speed of stone at the highest point is v(v gt sqrt(gl)) then its speed at the lowest point is

A block A of mass m_(1) is placed on a horizontal frictionless table. It is connected to one end of a light spring of force constant k whose other end is fixed to a wall. A small block B of mass m_(2) is placed on block A. The coefficient of static friction between the blocks is mu . The system is displaced slightly from its equilibrium position and released. What is the maximum amplitude of the resulting simple harmonic motion of the system so that the upper block does not slip over the lower block ?

A block of mass 1kg is attached to one end of a spring of force constant k=20N/m. The other end of the spring is attached to a fixed rigid support. This spring block system is made to oscillate on a rough horizontal surface (mu = 0.04). The initial displacement of the block from the equilibrium position is a =30cm. How many times the block passes from the mean position before coming to rest ? (g=10m//s^(2))
