Two clay balls collide and stick. Ball 1 has a mass of 1 kg and an initial velocity of 10 m/s in the positive x direction. Ball 2 has a mass of 4 kg and an initial velocity of 20 m/s in the negative x direction. What is the final velocity of the combined mass?

A 4.0 kg mess kit sliding on a frictionless surface explodes in two different sized parts, one has a mass of 3.0 kg and is moving with velocity (2i-3j) m/s, the other has a mass of 1kg and is moving at (-5i+10j) m/s. What is the original velocity (in vector notation) of the mess kit?

A 47.0 kg boy stands on a sled that is stopped in the middle of a frozen pond. The boy jumps horizontally off the sled with a velocity of 2.40 m/s. The sled moves in the opposite direction with a velocity of −11.1 m/s. What is the mass of the sled?

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 140,000 kg and a velocity of 0.300 m/s, and the second having a mass of 95,000 kg and a velocity of −0.120 m/s.  (The minus indicates direction of motion.) What is their final velocity (in m/s)?

Two cars approach an intersection which is covered in ice (and frictionless). The first car of mass m1 = 2600 kg is heading due east with an initial velocity of 22 m/s and the second car of mass m2 = 3000 kg is heading due north with an initial velocity of 33 m/s. What is the magnitude of the velocity of the two cars after they collide and stick together. m V2 Car 1 m2 +E Car 2

A space probe is traveling in outer space with a momentum that has a magnitude of 3.04 x 107 kg·m/s. A retrorocket is fired to slow down the probe. It applies a force to the probe that has a magnitude of 1.19 x 106 N and a direction opposite to the probe's motion. It fires for a period of 8.86 s. Determine the momentum of the probe after the retrorocket ceases to fire.

Four particles are arranged in a square with sides of 1.0 m. The bottom particles each have a mass of 1.0 kg. The center of mass of the system is located at Ycm = 0.25 m. The upper particles each have mass m. What is m?

Two cars collide at an intersection. Car A�, with a mass of 1900 kgkg , is going from west to east, while car B�, of mass 1300 kgkg , is going from north to south at 14.0 m/sm/s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 55.0 ∘∘ south of east from the point of impact.How fast were the enmeshed cars moving just after the collision?

Two carts on a straight track collide head on. The first cart was moving at 3.6 m/s in the positive x direction and the second was moving at 2.4 m/s in the opposite direction. After the collision, the second car continues moving in its initial direction of motion at 0.24 m/s. If the mass of the second car is 5.0 times that of the first, what is the mass and final velocity of the first car?

After skiding down a snow-covered hill on an inner tube, Ashley is coasting across a level snowfield at a constant velocity of +2.6 m/s. Miranda runs after her at a velocity of +4.5 m/s and hops on the inner tube. How fast do the two of them slide across the snow together on the inner tube? Ashley's mass is 54 kg, and Miranda's is 52 kg. Ignore the mass of the inner tube and any friction between the inner tube and the snow.
