A cylinder of mass m radius r is resting on a horizontal platform(parallel to xy plane) with its axis fixed along y axis and free to rotate about its axis .The platform is given a motion in the x direction given by :x=Acos(wt) m There is no slipping between the cylinder and the platform m The maximum torque acting on the cylinder during its motion isAns::1/2×MR(w)^2I already have the solution and method.But my doubt is why cant i use F=ma=MAw^2 find force and thenTorque=force(MRw^2)×dist(R)But then i get MRw^2 which is wrong

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.
