A particle of mass 0.1 Kg is executing simple harmonic motion of amplitude 1 m and time period 0.2 SEcond -The maximum force on the particle will be (1)9 N (2)99 N (3) 9.9 N (4) 0.99 N

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
