Always had a doubt. Suppose a block is kept on top of another block which is placed on ground. All surfaces are smooth. If the lower block is moved forward with any accl, then the block above it moves bckward with respect to the lower block. Though it is common sense but what is the real concept related to it. and what will be the accl of the above block.
Eg: Q- The masses of blocks A,B,C are 1,2, and 0.5kg. All surfaces are smooth. If force F=50 N acts as shown, then find the(1) force which A exerts on B
2)and the accl of C.
just do and explain the 2^nd part as clearly as you can

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.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
