V Puck mass = m Rod: Mass = 4m Rotational inertia = I Length = ( 11. The diagram above shows a top view of a long rod (length = 6, mass = 4m, rotational inertia = I, measured about the center of the rod) that sits at rest on its side on a frictionless table. A puck (mass = m) initially slides to the left with a speed v, strikes the rod, and bounces back to the right, moving at half its initial speed. Develop expressions for the linear speed (Vrod) and the rotational speed (@rod) of the rod immediately after the collision. a. Vrod = v/4 and @rod = mv//21 b. Vrod = 3v/4 and @rod = 3mv//21 C. Vrod = V/8 and @rod = mv//41 d. Vrod = 3v/8 and @rod = 3mv//41
