Question 1- A constant torque of |τ→| = 3N m acts on a solid object with a moment of inertia I = 12 kg m2. If the object starts from rest, find the work done if the torque acts for 4 s.
Question 2- Three point masses are connected by a massless rod and rotate about the x axis with an angular speed of 1.5 rad/s as shown in the figure. Find the Angular Momentum of this system.
