(02.07 MC)After the light turned green, a car accelerated from rest to 28.0 m/s. This happened over 4.23 seconds. If the total mass of the car is 1,876 kg, what was the magnitude of the net force to cause this acceleration?

(01.07 LC)A car travels 25.0 meters in the first 10.0 seconds of a trip and 40.0 meters in the next 10.0 seconds of the trip. What is the average speed of the car in meters per second for the total trip?

(03.05 MC)A 5.0-kg mass is moving to the right at 3.0 m/s. A 9.0-kg mass is moving to the left at 2.0 m/s. If after collision the two masses join together, what is their velocity after collision?
