While driving behind a car traveling at 5.85m/s, you notice that a tire has a hemispherical bump on its rim. The radius of the tire is approximately 25.4cm. (a) What is the bump's period of oscillation? (b) If the bump is located at a distance of 19.7cm from the axis of rotation, then what is the tangential velocity of the bump?

While driving down the street, your friend’s car was hit by a truck from behind.  The mass of your friend’s car is 1500 kg while the truck is 1800kg.  Your friend was driving 25 mph or 11.2 m/s. Assume that collision causes both cars to stick together and they do not supply additional power to the wheels after the collision. After the collision, the two cars slide to a stop. The coefficient of kinetic friction is 0.65 for the car and truck...
