Review Questions 1. A small car with a mass of 800. kg is moving with a velocity of 27.8 m/s. a. What is the momentum of the car? b. What velocity is needed for a 2400. kg car in order to have the same momentum? 2. A scooter has a mass of 250. kg. A constant force is exerted on it for 60.0 s.
The Law of Conservation of Momentum states that in a closed system, the total momentum of masses before and after . their collision is constant-momentum, which is conserved. This states that when two things collide the sum of the momentum will be the same before the collision as after.

And since we started with no momentum in the vertical direction initially, we have to end with no momentum vertically. So if the first sphere has three units of momentum vertically after the collision, then the second sphere has to have three units of momentum vertically downward after the collision, which gives us an answer of D.

Doctors see in hypnosis a possible answer to the rejection problem which surgeons meet when transplanting hearts and other organs. For items 11-20, choose the right answer A, B or C to complete the second sentence using the word given, so that it has a similar meaning to the first...Favorite Answer. Momentum IS always conserved. Even collisions between pool balls, momentum isn't 100% conserved either. When they hit, heat and sound is created which is a loss in kinetic energy so velocity speed is lost (even though mass is the same before and after collision).Basically, in a collision like the one you are trying to do, you want an elastic collision, in which both the kinetic energy and momentum are conserved. All momentum (P) is is mass * velocity, and Kinetic Energy (K) is 1/2*mass*velocity^2. In your situtation, I'm assuming everything has the same mass. If so, K = 1/2 * v^2. So, Kf = Ki and Pf = Pi.

It might not be obvious why this is useful, but momentum has this cool property where the total amount of it never changes. This is called the conservation of momentum, and we can use it to analyze collisions and other interactions. Bam! Momentum And Collisions. A particle of mass m is moving at velocity v . The linear momentum is defined as Conservation Of Linear Momentum. When two objects collide, momentum is conserved. The figure below shows a collision between two objects (before and after).
