Before a collision, Object A has a momentum of 15 kg*m/s and Object B has a momentum of 22 kg*m/s.  Then, Object A and Object B collide with each other.  After the collision, Object A has a momentum of 11 kg*m/s.  How much momentum does Object B have after the collision?  Explain your answer.

A ball weighing 10 kg is initially at rest, then suddenly explodes into 3 pieces. The picture shows the length and direction for each one of the three velocities. What were the length and direct of the ball before the explosion? Hint : use the momentum conservation principle on the y axis and x axis.

Two gliders are on a frictionless, level air track. Both gliders are free to move. Initially, glider A moves to the right and glider B is at rest. After the collision, glider A has reversed direction and moves to the left. The mass of glider A is one quarter of the mass of glider B. The system is defined as the two gliders.   Which object has the higher change in momentum? A Glider A B Glider B C They have the same change in momentum in both magnitude and direction D They have a change in momentum that is equal in magnitude but opposite in direction E Cannot determine

The table gives mass and speed data for the two objects in the figure. Find (a) the kinetic energy, (b) the magnitude of the momentum for object A and (c) the kinetic energy, (d) the magnitude of the momentum for object B. Object A Object B Mass 2.40 kg 5.00 kg Speed 5.00m/s 2.40m/s A 2.40 kg B 5.00 kg 5.00 m/s 2.40 m/s

Two objects are on a collision course. Object #1 has a mass of 13.4 kg and an initial velocity of 12.3 m/s i. Object #2 has a mass of 7.53 kg and an initial velocity of -3.69 m/s i. If the system is isolated and the objects stick together upon colliding, what amount of energy is lost in the collision?  Assume that all quantities are good to 3 significant figures, All numeric answers should be entered rounded to 3 significant figure.

Consider a garbage truck with a mass of 1.25 x 10^4 kg, which is moving at 10.5 m/s Part A. What is the momentum of the garbage truck in kilogram meter per second ? Part B. I would speed in meters per second would a 8.00 kg trash can have the same momentum as the truck ? 

It is generally a good idea to gain an understanding of the size of units. Consider each object and calculate the magnitude of their momentum in SI units. A ladybug with mass 28.50 milligrams flies by your head at 3.75 km/h. magnitude of the momentum: kg-m/s A 37.90 km boy walks at 4.05 km/h. magnitude of the momentum: kg-m/s A car with mass 841 kg is moving at a speed of 41.3 km/h. magnitude of the momentum: kg-m/s

In reviewing her lab book, a physics student finds the following description of a collision: " a 4 kg air hockey puck with an initial speed of 6 m/s to the right collided head on with a 1 kg puck moving to the left at the same speed. After the collision, both pucks traveled to the right, the 4 kg puck at 2 m/s and the 1 kg puck at 10 m/a." Is momentum conserved in this description? Is kinetic energy conserved on this description ? Could this collision actually have taken place as described?  Source: physics: a conceptual world view

Need help with this physics question !

As shown in the figure below, cars #1 and #2 are travelling across a horizontal surface. The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m, = 14.5 kg and m, = 45.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during, and after the collision. Determine the velocity of car #2 before the collision. You may ignore friction and treat the wheels of the cars as massless. 922 You have been given the mass of car #1 and the graph provides you with the momentum of the car after the collision. See if you can use this information to determine the velocity of car #1 after the collision. Knowing the velocity of car #1 after the collision and also knowing that the two cars are coupled together, see if you can determine the velocity and hence momentum of car #2 after the collision.…
