Explain why momentum is always conserved in both Elastic and Inelastic collision?

Two rolling carts are moving toward each other at the same speed. Cart 1 has a mass m1 =200g and Cart 2 has a mass m2 =400g. Draw a velocity vector v → for each cart. Momentum p → is a vector defined as p → = m v →. Draw a momentum vector for each cart. Then add the two momentum vectors together to find the total momentum, vector P total =vector p1 + vector p2

Problem 3: An egg with a mass m is dropped from rest from a height h and falls to the ground and breaks. Part (a) Write an expression for the magnitude of the net impulse imparted to the egg as it is stopped by the floor. Your expression will be in terms of m, h, and g. Neglect air resistance. Expression : J = Select from the variables below to write your expression. Note that all variables may not be required. B, y, 0, b, c, d, e, g, h, j, k, m, n, P, S Part (b) What is the numeric value for the magnitude of the impulse if m = 0.045 kg and h = 1.6 m Numeric : A numeric value is expected and not an expression. J =

a) What is the total momentum of this two-astroid system? (Give answer in component form). Don’t forget to include appropriate units in your answers!

A certain carbon monoxide molecule consists of a carbon atom of mass mc = 14 u and an oxygen atom of mass mo = 18 u that are separated by a distance of d = 122 pm, where "u" is an atomic unit of mass. a. Write a symbolic equation for the location of the center of mass of the carbon monoxide molecule relative to the position of the oxygen atom. This expression should be in terms of the masses of the atoms and the distance between them.  b. Calculate the numeric value for the center of mass of carbon monoxide in units of pm.

A projectile has undergone an elastic one-dimensional collision with an initially stationary target, along an x axis. The figure below is a graph of position versus time for the projectile and target, before and after the collision. (Two line segments are parallel to the time axis.) Which is true about the masses of the projectile and target? 4 O the projectile's mass is greater O the target's mass is greater O the masses are equal

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at vi = 4.40 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 8 = 40.0° with the horizontal axis while the green disk makes an angle of = 50.0° with this axis as in Figure b. Determine the speed of each disk after the collision. of=1 m/s m/s Vgf= Before the collision After the collision. b of Ⓡ

Two objects, A and B, with masses 3.2 kg and 1.8 kg, move in a frictionless horizontal surface. Object A moves to the right at a constant speed of 5.1 m/s while object B moves to the right at a constant speed of 1.4 m/s.  They collide and stick together. a) Find the total kinetic energy of the system after the collision. b) Is the kinetic energy of the system conserved?  Explain.
