а. Mass b. Velocity С. Time d. Impulse е. Momentum f. Energy g. Distance h. Acceleration Identify the quantity of the given units. Choose from the choices above. 1. m/sec south 2. kg m/sec 3. km/hr 4. m/sec? 5. m/s/s

hint: momentum is conserved in the horizontal direction. You may use any of the three methods ( force-inertia, impulse-momentum, work-energy)

What is the equation for change of momentum inelastic collision. I’m not understanding it. I know you multiply mass times velocity and then add the other. But where do you divide

(The complete question is in the picture) Which of the following statements about elastic and inelastic collisions is TRUE?A. The kinetic energy is not conserved for both collisions.B. The momentum is not conserved for both collisions.C. The momentum in an elastic collision is conserved, but not conserved in an inelastic collision.D. The kinetic energy in an elastic collision is conserved, but not conserved in aninelastic collision.

1. If the collision is elastic what is the final velocity of cart 1? What about cart 2? 2 if the collision was perfectly inelastic, what would the final velocity of the two carts be?

Josh is driving his car home after going to work. However, he fell asleep while driving because of fatigue from working 12 hours. He accidentally hits another car. His initial velocity was 40.2 m/s and after 5.6 s at the moment of the crash, his velocity was 38.6 m/s. Compute for the following: a. Momentum before the collisionb. Momentum after the collisionc. Impulsed. Force

Which of the following describes kinetic energy and momentum before and after a perfectly elastic collision? (K:1) KINETIC ENERGY MOMENTUM A. Not Conserved Not Conserved B. Not Conserved Conserved C. Conserved Not Conserved D. Conserved Conserved Select one: OA Ο Ο.Ο AD C B

5. A ball of mass 25 g traveling east at 12 m/s bounces elastically into a 2nd ball of mass 50 g that is traveling west at 4m/s. What are the final velocities and momentum of each ball? (Hint: either solve the systems of equations for momentum and energy simultaneously or come up with a relative velocity system...) see # 3

Ballistic Pendulum B. Vo When a projectile is fired into a box, momentum is transferred. If the box is dangling on a string, it will swing like a pendulum. Suppose a 1 gram Nerf projectile is fired into a 25 gram empty Kleenex box several times, and on average the box swings back 6 degrees from the impact. The length of the string is 0.8 meters. 1) What kind of collision is this? How do you know?

What is momentum? Is momentum a vector or a scalar? Is momentum always conserved? What is the relationship between momentum and center of mass? What is the impulse? What are the similarities and differences between impulse and work?

As shown on the right two identical objects have the same mass. They are moving with the same speed but one is going due North and the other is going due East. Which of the following statements is completely correct? North a. East m m V Select one: They both have the same kinetic energies and the same momentum. b. They have different kinetic energies and they have different momentum. OC. They have the same kinetic energies, but they have different momentum. Od. They have different kinetic energies, but they have the same momentum.
