From F.B.DTotal acceleration=f÷[M1+m2+M3)=f/6.For 3kg block:N2=M3*a=f/2For 1kg block:f-N1=M1*a.=>N1=5f/6For 2kg block:Fr1+Fr2=m2*g=>0.2*5f/6+0.5*f/6=20=>F=80N

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?
