Acar (mass = 1200 kg) is traveling at 31.1 m/s when it collides head-on with a sport utility vehicle (mass = 2830 kg) traveling in the opposite direction. in the collision, the two vehicles come to a halt. at what speed was the sport utility vehicle traveling?

13.18 m/s

Explanation:

Let the velocity of sports utility car is

-u as it is moving in opposite direction.

mc = 1200 kg, uc = 31.1 m/s

ms = 2830 kg, us = - u = ?

Using conservation of momentum

mc × uc + ms × us = 0

1200 × 31.1 - 2830 × u = 0

u = 13.18 m/s

answer; the correct answer is technician a; ///100%good luck

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
