a car (m1=2000kg) is traveling east with a velocity of 20i m/s. this car collieds with a second car (m2=1500kg) that is traveling north with a velocity 20j m/s. these 2 cars tangle together when they collide.

what was the total kinetic energy before the collision?

what is the magnitude of the momentum of the 2 cars (as 1 system)?

what is the speed of the combined mass just after the collision?

what is the direction traveled in degrees?
