A 1800 kg mass car is traveling south at a velocity of 15 m/s through an intersection. It is hit by a 3500 kg mass car traveling east at 20 m/s. If the two cars collide and become one object (perfectly inelastic). What will be the final displacement of the cars after the ...

**Physics - elastic collision**

Car A, with mass of 1735kg, was traveling north at 45.5km/h and car B, with a mass of 2540kg, was traveling west at 37.7km/h when they collided at an intersection. if the cars stuck together after the collision, what was their combined momentum? Was the collision elastic or ...

A car weighs 15000-N and is traveling along a highway at 27 m/s. If the driver immediately applies his brakes and the car comes to rest in 85 m, what net force acts on the car during its acceleration? How do you solve this to get an answer of -6564N? Thanks!
