A car (mass = 1090 kg) is traveling at 25 m/s when it collides head-on with a sport utility vehicle? - utility car
A car (mass = 1090 kg) is moving 25 m / s when it hits head on with a sport utility vehicle (mass = 2280 kg) in the opposite direction. In the collision both vehicles came to a standstill. How fast the SUV was traveling?

Hello Brian. This is not a problem of kinetic energy. It's all about speed. As the two vehicles had zero momentum after the collision, the vehicles must have the same momentum before the collision.
Momentum = mass x velocity
The dynamics of Car = SUV dynamics, ie:
(1090) (25) = (2280) (V)
Solution v is 11.95 m / s velocity sports utility vehicle.
Best wishes and good luck.
