Question

A car with a mass of 1.5 × 10³ kilograms is traveling west at a velocity of 22 meters/second. It hits a stationary car with a mass of 9.0 × 10Æ kilograms. If the collision is inelastic, what is the final direction and approximate velocity of the two cars?

A. 14 METERS/SECONDS TO THE WEST
B. 14 METERS/ SECONDS TO THE EAST
C.22 METERS/SECOND TO THE EAST
D. 22 METERS/SECONDS TO THE WEST

Answer 1

A. 14 METERS/SECONDS TO THE WEST

Step-by-step explanation:

Answer 2

Among the choice above the answer is A which is 14 meters per seconds to the west. You can deduce the answer here without any calculations based on the choices you have. First, the car is traveling west and hits a stationary car, so its direction at the end will be west since you're not given any aditional information. The problem states it's an inelastic collision so kinetic energy is not conserved but momentum will be. The car will slow down as a result of the collision. T
