A 1500 kg car is parked in the street out in front of the house. The driver pulls out to go to the grocery store and in 15 seconds has reached a speed of 45 m/s. The car maintains a constant speed of 45 m/s, going around a wide curve and then down a straight road until it comes to a red light. The car takes 25 seconds to come to a complete stop at the red light. The store is 2000 m past the red light, and once the light turns green, the driver arrives at the store in 5 minutes. What is the momentum of the car while parked out in front of the house?
