Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 2) 10.0 points In a particular crash test, an automobile of mass 1431 kg collides with a wall and bounces back off the wall. The x components of the initial and final speeds of the automobile are 16 m / s and 1 . 7 m / s, respectively. If the collision lasts for 0 . 14 s, find the magnitude of the impulse due to the collision. Answer in units of kg · m / s. 002 (part 2 of 2) 10.0 points Calculate the magnitude of the average force exerted on the automobile during the colli sion. Answer in units of N. 003 (part 1 of 2) 10.0 points A force of 7 . 85 N acts on a(n) 2 . 1 kg object for 16 . 3 s. What is the object’s change in momentum? Answer in units of N · s....
