1. Automobile collision[Page 171 ( of text book):
Note the threshold conditions described and study the problem given there. Then apply the momentum impulse equation to determine the force and acceleration a person of your mass and size (do not use the numbers given in the problem; use your own set of numbers; must be different for each student) will experience in a head-on collision and discuss the injury caused by the collision. Also comment on what type of collision is applicable there.

Use the worked example above to help you solve this problem. In a crash test, a car of mass 1.44 103 kg collides with a wall and rebounds as shown in the figure. The initial and final velocities of the car are vi = -15.2 m/s and vf = 2.11 m/s, respectively. If the collision lasts for 0.153 s, find the following. (a) the impulse delivered to the car due to the collision kg · m/s (b) the size of...
