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.

A 81.1 kg blue bumper car and rider are traveling at 8.1 m/s. They rear end a red bumper car of mass 71.3 kg traveling in the same direction at 7.2 m/s. If the blue bumper car continues forward at 2.8 m/s, what is the velocity of the red bumper car? Round your answer to 1 decimal place, include units.
Lions can run at speeds up to approximately 80.0 km/h. A hungry 109 kg lion running northward at top speed attacks and holds onto a 39.0 kg Thomson's gazelle running eastward at 75.0 km/h. Find the final speed ?fvf of the lion‑gazelle system just after the lion attacks. vf=? in m/s
A 2.4-kg cart is rolling along a frictionless, horizontal track towards a 1.3-kg cart that is held initially at rest. The carts are loaded with strong magnets that cause them to attract one another. Thus, the speed of each cart increases. At a certain instant before the carts collide, the first cart's velocity is +4.0 m/s, and the second cart's velocity is -2.5 m/s. (a) What is the total momentum of the system of the two carts at this instant? (b) What was the velocity of the first cart when the second cart was still at rest? (a) Number (b) Number i Units Units
An amusement park features a set of light railcars, currently resting on a straight, level section of track. Each railcar has a mass of 18 kg. Ellen and her younger brother Tim are seated in two of these railcars, which are initially at rest with the rubber buffers just touching each other. Ellen's mass is 42 kg, while Tim's mass is 32 kg. Ellen pushes Tim's railcar so that it moves away with a speed of 3.0 m/s relative to the track. Assuming that the frictional forces on the railcars are small, how far the railcars will have travelled after 2.0 s?
An astronaut of mass 65.0 kg is at rest relative to her space vehicle with nothing behind her except the empty,dark, vacuum of space. Another astronaut decides to play a practical joke on her and throws a 10.0 kg anvil(because those are totally used in space) at her with a velocity of 3.00 m/s. How fast do she and the anvil moveonce she catches it? Just to lower your anxiety, there is a way for her to get back to the space vehicle
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 135,000 kg and a velocity of −0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)? (Enter a number.) m/s
