A rigid ball of mass m and velocity u undergoes an inelastic collision with another rigid ball of mass m and velocity -u. After the collision, the balls stick together. Find the mass of the composite object after the collision. What must |u| be for the composite object mass to be 3m?

A soccer ball of 4.40925 (2 kilosg) pounds moves to the right a speed of 0.5 m/s.  Hits a 0.1102311 (0.05 kilosg) pounds tennis ball initially moving to the left at 2 m/s.  The collision is elastic and takes place in one dimension, along the x axis. What is the speed of the center of mass, vcm?

Two clay balls collide and stick. Ball 1 has a mass of 3 kg and an initial velocity of 10 m/s in the positive x direction. Ball 2 has a mass of 10 kg and an initial velocity of 12 m/s in the negative x direction. What is the final velocity of the combined mass?

A puck of mass mA that is moving along the +x axis with speed va collides with another puck of mass mB = 2mA. The collision is not head-on, so that after they collide, mB is located at 45◦ south of east, while mA collides head-on elastically with a stationary puck of mass mC = 3mA. If, after the second collision, the final velocity of mC is 0.450 [m/s], 25◦ north of east, what is the initial speed va?

A joelshawon is a subatomic particle with a mass of 15.7g and it is made of a Joelon (mass 7.6g) and a Shawon (mass 8.1g). A joelon going 3.6 x 10^6 m/s to the east collides with a shawon going 1.1 x 10^6 m/s to the North. Determine the speed and direction of the resulting joelshawon

A 13.8 kg block is sliding along a frictionless surface with a speed of 95.7 m/s. It collides with a second block of mass 93.1 kg. The second block is initially at rest. After the collision, the first block has rebounded with a speed of 26.1 m/s. If this collision is one dimensional, what is the speed in (m/s) of the second block after the collision?

A ball of mass 0.34 kg moving with a speed of 2.7 m/s to the right collides head on with a 0.24 kg ball at rest. If the collision is elastic, what is the speed and direction of each ball after collision?

If a mass of 1 kg with an initial velocity of 4 m/s to the right collides elastically with a mass of 3 kg going 1 m/s to the left, what will be the velocity of the first mass after the collision? Right is positive, left is negative. Options include: + 1.0 m/s -2.5 m/s -1.5 m/s -3.5 m/s

A mass of m1= 4 kg moving with a velocity of v1=(2 m/s)ˆi (positive x−direction) collides with another mass, m2 moving at v2= (−4 m/s)ˆi (negative x−direction). The masses collide and stick together, moving off with a velocity of v= (−2 m/s)ˆi. What is m2? A)m2= 4 kg B)m2= 8 kg C)m2= 12 kg D)m2= 16 kg

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.
