Question

Two particles with masses m and 5m are moving toward each other along the x axis with the same initial speeds vi. Particle m is traveling to the left, while particle 5m is traveling to the right. They undergo an elastic, glancing collision such that particle m is moving in the negative y direction after the collision at a right angle from its initial direction.

(a) Find the final speeds of the two particles in terms of vi.

particle m: ____________ ✕ vi
particle 5m: ____________ ✕ vi


(b) What is the angle θ at which the particle 5m is scattered?

    Two particles are moving along the x axis. Particle 1 has a mass m1 and a velocity v1 = +4.5 m/s. Particle 2 has a mass m2 and a velocity v2 = -7.3 m/s. The velocity of the center of mass of these two particles is zero. In other words, the center of mass of the particles remains stationary, even though each particle is moving. Find the ratio m1/m2 of the masses of the particles.

    Two shuffleboard disks of equal mass, one orange and the other yellow, are involved in a glancing collision. The yellow disk is initially at rest and is struck by the orange disk moving with a speed vi. After the collision, the orange disk moves along a direction that makes an angle theta with its initial direction of motion. The velocities of the two disks are perpendicular after the collision. Determine: 1) the final speed of each disk; 2) whether the...

    Collisions Quiz Name 1. The figure shows an overhead view of two particles sliding at constant velocity over a frictionles surface. The particles have the same mass and the same initial speed, and they collide where their paths intersect. An x axis is arranged to bisect the angle between their incoming paths. The region to the right of the collision is divided into four lettered sections by the x axis and four numbered dashed lines. Along what line, or in...

    POD24-Prob#2) Particle Physics-where collisions are everything One important way that the physics of collisions is used is in the study of particle physics-understanding matter at its most fundamental level. To do this, scientists look at trails left by particles after a collision, like the one shown to the right. Consider how this might work in a simple two particle collision- Let's say a proton (P1) is headed toward another proton (P2). The first proton has a velocity of 3.5x10sm/s. P2...
