Use the worked example above to help you solve this problem. A car with mass 1.40 x 103 kg traveling east at a speed of 29.4 m/s collides at an intersection with a 2.56 x 103 kg van traveling north at a speed of 18.3 m/s, as shown in the figure. Find the magnitude and direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (that is, they stick together) and assuming that friction between the vehicles and the road can be neglected.

A mass of 2.13 kg is traveling in the +x direction with velocity 4.10 m/s. It collides with a stationary mass of 8.94 kg and the collision is elastic. What is the velocity of the 2.13 kg mass after the collision in m/s? p.s Show step by step please.

Please asap

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 180,000 kg and a velocity of 0.300 m/s, and the second having a mass of 125,000 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

Plz solve

Can you please answer question 2 and show all of the steps

Please show complete and detailed solution with illustration for both questions.  A ball is hanging from a cord of negligible weight. A secondary ball with the same weight as the first ball is measured 3m above the hanging ball, and just touching the cord, us released from rest and gains its velocity before striking the hanging ball. If the friction is negligible and the impact is perfectly elastic, compute the magnitute and direction of the velocity of the secondary ball in terms of its velocity before contact. The Dead Sea has been found to have seawater with a unit weight of 75lb/ft3; glycerin has a specific gravity of 1.26 and honey has a density of 1450kg/m3. If each liquid was poured into the a beaker one at a time without mixing, what would be the order of the liquids from the bottom of the beaker? Prove your answer.

What is the correct answer to this and why? Please provide an in depth explanation explaining the various aspects you need to know for this question and a step by step solution.

Show calculation and write down what is given and known.  draw a sketch of the system if needed 1. A 10-g bullet moving horizontally strikes and passes through a 4.0-kg block moving with a speed of 4.2 m/s in the opposite direction on a horizontal, frictionless surface. If the block is brought to rest by the collision, and the bullet emerges with a speed of 320m/s, what is the initial speed of the bullet?

Please answer all the parts of the question
