A Vulcan spaceship has a mass of 6.50 × 104 kg and a Romulan spaceship is twice as massive. Both have engines that generate the same total force of 9.50 × 106 N.

a.) If each spaceship fires its engine for the same amount of time, starting from rest and ignoring any change in mass due to whatever is expelled by the engines, calculate the energy of the Vulcan spaceship if the engines are fired for 103 s.

B.)If each spaceship fires its engine for the same distance, starting from rest and ignoring any change in mass due to whatever is expelled by the engines, calculate the momentum of the Romulan spaceship if the engines are fired for 103 m.
