A car of mass 1000 kg is moving with a velocity of 20 m/s. After a collision with another car of mass 1500 kg at rest, find the final velocity of both cars assuming conservation of momentum.
💡 Hint: Use the momentum conservation equation.
A disk rotates about its center. If the radius is doubled while keeping the mass the same, explain how this affects its moment of inertia.
💡 Hint: Consider how radius affects inertia.
