A truck of mass 3000 kg3000\,\text{kg} is moving at 10 m/s10\,\text{m/s}. A scooter of mass 100 kg100\,\text{kg} is moving at 20 m/s20\,\text{m/s}. Which statement is true about their momenta? (a) Their momenta cannot be compared without knowing the time of travel (b) The truck has greater momentum than the scooter (c) The scooter has greater momentum than the truck (d) The scooter has greater momentum because its higher speed more than compensates for its smaller mass
