Two particles with masses 2m and 8m are moving toward each other along the x axis with the same initial speeds vi. Particle 2m is traveling to the left, while particle 8m is traveling to the right. They undergo an elastic, glancing collision such that particle 2m 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 2m                   ✕ vi particle 8m                    ✕ vi (b) What is the angle ? at which the particle 8m is scattered

A particle of mass m1 undergoes a one-dimensional elastic collision with a particle of mass m2 = 2m1 that is initially at rest.  If particle 2 recoils at speed v2 = 1200 m/s, what is the speed of particle 1 before the collision?

1. Particle 1 has mass m1= 5 kg and velocity v1= 30 m/s. Particle 2 is at rest and has m2= 3 kg. Given that the velocity of particle 1 after the collision is v1= 7.5 m/s : a. Find the velocity (v2) of particle 2 after the collision B. Draw a diagram(arrows) representing the masses and velocities before and after the Collision.

A firecracker sits at rest on a frictionless floor and explodes into three pieces. The velocities of two pieces are shown below; these particles have equal speed after the explosion. √1 1 √2 If Piece 2 is twice as massive as Piece 1, which choice shows the direction of Piece 3's velocity after the explosion? 0

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 Ⓡ

Need help checking a practice problem. Thanks!

After the ball A hits (or collides with) the ball B, they are both observed to move off at 45° to the x axis,ball A above the x axis and ball B below. So ?′A= 45° and ?′B = −45°.Is the collision elastic? Justify your answer

A particle of mass m₁ and velocity v₁ hits the stationary particle of mass m2. After the collision, the outgoing speeds of these particles are equal. Considering elastic collision what is the angle between velocities of the particles after collision? Mass m₁ = 2m2.

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 vOi = 5.80 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of ? = 34.0° with the horizontal axis while the green disk makes an angle of ? = 56.0° with this axis as in Figure b. Determine the speed of each disk after the collision.

Two objects of equal mass collide. Object A is initially moving with a velocity of 15 m/s in the +x-direction, and object B is initially at rest. After the collision, object A is at rest. There are no external forces acting on the system of two masses. (a) Use momentum conservation to deduce the velocity of object B after the collision. (b) Is this collision elastic?
