Cars are equipped with air bags to prevent occupants from colliding with a dashboard or windshield. A 50-kg person moving at 20 m/s will be considerably safer if their momentum is stopped by an air bag instead of by a dashboard or windshield. Why does an air bag contribute to the safety of the person? O It causes the momentum change and impulse experienced by the person to be less. O It causes the momentum change and the collision force to be less. O It causes the collision time to be greater and the collision force to be less.

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at vi = 4.40 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 8 = 40.0° with the horizontal axis while the green disk makes an angle of = 50.0° with this axis as in Figure b. Determine the speed of each disk after the collision. of=1 m/s m/s Vgf= Before the collision After the collision. b of Ⓡ
V ? A hockey puck of mass 4m has been rigged to explode, as part of a practical joke. Initially the puck is at rest on a frictionless ice rink. Then it bursts into three pieces. One chunk, of mass m, slides across the ice at speed v. Another chunk, of mass 2m, slides across the ice at speed 2v, in a direction at right angles to the direction of the first piece. From this information, find the velocity of the final chunk. Initally at rest

An oatmeal cookie is dropped on the floor. Is this an inelastic collision? Why or why not? It is because the cookie and floor can be considered one object. It is because the cookie and floor are stuck together. It is not because there is not momentum involved. It is not because the cookie and floor do not move away together as a unit.
An insurance company is testing air bag safety. Car A has front air bags and Car B does not. In both cases, the cars are driven into a brick wall with the same momentum. In Car A, the dummy survives, but in Car B, the dummy does not. In terms of impulse and force, please explain this result. The dummy in Car B experienced a greater impulse and a greater force than in Car A. O The dummy in Car B experienceda greater impulse but the same force as in Car A. The dummy in Car B experienced the same impulse but a greater force than in Car A. O The dummy in Car B experienced the same impulse and the same force as in Car A. O Not enough information to determine.
To apply shock loading to an artillery shell, a 20-kg pendulum A is released from a known height and strikes impactor B at a known velocity v0 . Impactor B then strikes the 1-kg artillery shell C . Knowing the coefficient of restitution between all objects is e, determine the mass of B to maximize the impulse applied to the artillery shell C.

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at vOi = 5.80 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of ? = 34.0° with the horizontal axis while the green disk makes an angle of ? = 56.0° with this axis as in Figure b. Determine the speed of each disk after the collision.
During a head on collision the car's airbags are intended to: O Decrease the speed of the vehicle prior to the accident. Decrease the impulse of the accident on the passengers, by decreasing the force the impact. Match the impact force of the passenger to what the vehicle is colliding with. O Decrease the force of impact on the passengers by keeping the impulse constant.

O Object 1 will bounce back with half its original speed while object 2 will move with a speed 0.5v1. O Object 1 will be moving with half its original speed while object 2 will be moving with a velocity equal to v₁.
A little fish has mass 0.400 kg and is floating motionlessly in the water, minding its own business, when a big fish (mass 2.00 kg) comes along and swallows it whole. If the big fish was gliding along at a constant velocity of 1.25 m/s before it swallowed the little fish, what will its velocity be immediately after the "collision"? O 1.04 m/s 7.50 m/s 1.50 m/s 0.250 m/s
