Rotational Inertia of Irregular Plate
Homework Statement In Fig. 10-43a, an irregularly shaped plastic plate with uniform thickness and density (mass per unit volume) is to be rotated around an axle that is perpendicular to the plate face and through point O. The rotational inertia of the plate about that axle is measured with the...- Nikolan

What Are the Initial Speeds of Two Cars After a Rear-End Collision?
Thank you very much! I ended up taking what you said and applying it like this: (Using this solution for both cars A and B) Fk = (uk)FN to find force of friction. W of Friction = (Fk)(D) = Kf - Ki = 1/2mvf^2 - 1/2mvi^2 to get: W = - 1/2mvi^2 => sqrt(((-2)(W))/M) for initial speeds of both...- Nikolan

What Are the Initial Speeds of Two Cars After a Rear-End Collision?
Homework Statement In the "before" part of Fig. 9-60, car A (mass 1100 kg) is stopped at a traffic light when it is rear-ended by car B (mass 1500 kg). Both cars then slide with locked wheels until the frictional force from the slick road (with a low μk of 0.21) stops them, at distances dA =...- Nikolan
