A contractor plans to install two slides for the children to play in a park. For the children below the age of 5 years, she prefers to have a slide whose top is at a height of 1.5 m, and is inclined at an angle of 30^@ to the ground, whereas for elder children, she wants to have a steep slide at a height of 3m, and inclined at an angle of 60^@ to the ground. What should be the length of the slide in each case?

A ring of mass M hangs from a thread and two beads of mass m slides on it without friction. The beads are released simultaneously from the top of the ring and slides down in opposite sides. Show that the ring will start to rise, if mgt(3M)/(2) . ltbr.

Two plates 1 and 2 move with velocities -v and 2v respectively. If the sphere does not slide relative to the plates, assuming the masses of each body as m , find the kinetic energy of the system (plates+sphere).

The mass in the fig. can slide on a frictionless surface. The mass is pulled out by a distance x . The spring constants are k_(1) and k_(2) respectively. Find the force pulling back on the mass and orce on the wall.

The one end of a 20 m long ladder is on the floor and the other end is in the contact of vertical wall. Its lower end slides on the floor. Show that the rate of sliding of the upper end is 4/3 times the rate of sliding the lower end when the lower end is 16 m away from the wall.

Figure shows a block of mass 2m sliding on a block of mass m. Find the acceleration of each block . ( All surface are smooth )
