Two particles are moving toward each other along the x axis with equal speeds. Specifically, particle 1 of mass 7 kg moves to the right at 3.87 m/s and particle 2 of mass 15 kg moves to the left at the same speed. The particles collide elastically. After the collision, the first particle moves at 90◦ to its original direction while the second particle is deflected through a smaller angle θ2 < 90◦.

A) Find the final speed of particle 1. (m/s)

B) Find the deflection angle that particle 2 experiences (in relation to particle 1's x-axis movement). (Degrees)

A mass (m) moves along the x-axis with velocity 2v. Another particle of mass (2m) moves with velocity v along the y-axis. 1) If the two objects collide inelastically and merge, how much kinetic energy is lost to heat? 2) If instead they collide elastically and it turns out that m still moves purely along the x-axis, what is it's velocity in the final state? It may help to find the velocities of these particles in the center of mass...

Two particles approach each other with equal and opposite speed v. The mass of one particle is m, and the mass of the other particle is nm, where n is just a unitless number. Snapshots of the system before, during, and after the elastic collision are shown above. After the collision the first particle moves in the exact opposite direction with speed 2.40v, and the speed of the second particle is unknown. What is the value of n?

Two particles move along an x axis. The position of particle 1 is given by x = 10.0t2 + 6.00t + 4.00 (in meters and seconds); the acceleration of particle 2 is given by a = -9.00t (in meters per seconds squared and seconds) and, at t = 0, its velocity is 24.0 m/s. When the velocities of the particles match, what is their velocity?
