For this problem, first of all we'll determine the position of centre of mass of given body.
After this we'll show all the external forces on the body and then further calculations will be done...
All the calculations are shown in the images below ::
Hope you got the concept well...!!!

A particle of mass m is attached to one end of a light slender rod which pivots about a horizontal axis through point O. The spring constant k-200 N/m and the distance b-200 mm. If the system is released from rest in the horizontal position shown where the spring is unstretched, the bar is observed to deflect a maximum of 30° clockwise. Determine (a) the particle mass m and (b) the particle speed v after a displacement of 15° from...

An elastic string of negligible mass has one end fixed to a
ceiling at point A. The other end, point B, which is attached to a
particle of mass 3 kg, is in a position such that it is vertically
below point A, with the distance AB equal to 0.7 m. The mass is
released from rest. If the modulus of elasticity of the string is
35 N and its natural length is 1.3m find i) The distance of the...

A uniform slender bar of mass M = 3.2 kg and length L = 1.78 m is translating on the smooth horizontal x-y plane with a velocity vm= 1.80 m/s when a particle of mass m = 0.36 kg traveling with a velocity Vm=5.52 m/s as shown strikes and becomes embedded in the bar. Determine the final linear velocity of the center of mass of the system and the angular velocity of the bar with its embedded particle. 3L 4...
A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass.
A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k = 75 N/m and negligible mass. At time t = 0 the mass is released from rest at a distance d = 0.35 m below its equilibrium height and undergoes simple harmonic motion with its position given as a function of time by y(t) = A cos(wt - φ). The positive y-axis...
