So this question is to be dealt through non inertial frame of reference using the concept of pseudo force.

Draw fbd of block m2

The eqn would be - m2*a*cos beta = T + m2*g*sin beta ....(I)

Here m2*a*cos beta is the component of pseudo force that is acting at an angle beta opposite to initial direction of acceleration

Now draw fbd of block m1-

The eqn would be - T + m1*a*cos alpha = m1*g*sin alpha.... (II)

Here m1*a*cos alpha is the component of pseudo force acting at an angle alpha opposite to the direction of initial acceleration.

On combining both equations

a= m2*g*sin beta + m1*g*sin alpha / m1*cos alpha + m2* cos beta

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?
