Q. A body of mass 200 g is acted upon by a force of 20 n. Find the acceleration of the body. If the body above is having a volume of 1000 cm3 estimate its density in kg/m2.
Q. A circular disk with a rectangular hole has a radius of 0.65 m and mass of 0.440 kg. It is suspended by a point on its perimeter. The moment of inertia about this point is I_p = 2.50×10-1 kgm2. Its center of mass is located at a distance of s=0.120 m from the center of the circle as shown. If the disk is allowed to oscillate side to side as a pendulum, what is the period of oscillations?
