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...
Q1 A small object with a momentum of magnitude 2.71 kg m/s approaches head-on a large object at rest. The small object bounces straight back with a momentum of magnitude 6.19 kg m/s. What is the magnitude of the small object's momentum change in kg m/s? Q2 A force acts on a 4.708 kg mass as follows: the force starts at zero and rises to 60.334 N linearly in 2.24 seconds, it remains at 60.334 N for another 5.756 seconds,...
. A 5.03 g nickel is dropped from the top of the Shanghai Tower in Lujiazui, Pudong, Shanghai and lands on the head of a person that is a distance of 632 m below. Just before the nickel hits the person's head, it is falling at a speed of 48.19 distance of 3.61 mm. The nickel comes to a complete stop in the person's head after penetrating a A) Determine the acceleration of the nickel after it strikes the head...
n a crash test, a truck with mass 2000 kg traveling at 23 m/s smashes head-on into a concrete wall without rebounding. The front end crumples so much that the truck is 0.62 m shorter than before. (a) What is the average speed of the truck during the collision (that is, during the interval between first contact with the wall and coming to a stop)? vavg= m/s (b) About how long does the collision last? (That is, how long is...
5. An automobile of mass 1500 kg moving at 25.0 m/s collides with a mass 4500 kg at rest. The bumpers of the two vehicles lock together the crash. a. Compare the force exerted by the car on the truck with that exerted truck on the car during the collision. Is one force larger than the are they equal in magnitude to each other? b. What is the final velocity of the car and truck just after the collision? Show your calculations. 6....
Momentum collision A person (m=67kg) is moving down a path at 3.4m/s when you collide, elastically, with another person (m=75kg) who was running directly toward you at 6.5m/s. What are each of your velocities after the collision?
The head of a golf club (of mass 250 g) is traveling at 44 m/s just before it strikes a 50 g golf ball (which is initially at rest). After the collision, the club head travels (in the same direction) at 36 m/s. a) Assuming momentum is conserved in the collision, find the speed of the golf ball just after the impact. (5 points) b) How much energy was lost in this collision? (5 points)
