In a particular crash test, an automobile of mass 1295 kg collides with a wall and bounces back off the wall. The x components of the initial and final speeds of the automobile are 25 m/s and 1.5 m/s, respectively.

Question

If the collision lasts for 0.11 s, find the magnitude of the impulse due to the collision.
Answer in units of kg · m/s.

Answer 1

impulse=mass(change velocity)
= mass(25+1.5)
