A car with a total mass of 1.37 103 kg has wheels of radius 34.0 cm and moment of inertia 0.785 kg · m2. (a) Find the car's translational kinetic energy when the car is moving at a speed of 28.5 m/s. (b) Find the car's rotational energy when the car is moving at a speed of 28.5 m/s.
A car with mass MC = 1.26 x 103 kg runs into the back of a truck with mass MT = 3.23 x 103 kg that is initially at rest. Immediately after the collision, the car is moving with a speed of 1.09 m/s and the truck is moving with a speed of 3.29 m/s, both in the direction the car was initially traveling. What is the total kinetic energy lost in the collision? (Of course, the change in energy...
