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

An pickup truck with mass 1.85  103 kg is traveling eastbound at +14.7 m/s, while a compact car with mass 8.55  102 kg is traveling westbound at -14.7 m/s. (See figure.) The vehicles collide head-on, becoming entangled. (a) Find the speed of the entangled vehicles after the collision. (b) Find the change in the velocity of each vehicle. Δvtruck= ? m/s Δvcar= ? m/s

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 railroad freight car rolls on a track at 2.80 m/s toward two identical coupled freight cars, which are rolling in the same direction as the first, but at a speed of 1.20 m/s. The first reaches the second two and all couple together. The mass of each is 3.10 ✕ 104 kg. Find the (absolute value of the) amount of kinetic energy (in J) converted to other forms during the collision.

Skater A, with a mass of 72.0 kg, is moving at 11.0 m/s [S] when he collides with skater B, with a mass of 42.0 kg, moving at 14.0 m/s [E]. The collision is completely inelastic and the two skaters move off together after the collision. Find the velocity of the skaters, right after the collision. Can you please explain why in the calculation vAy = - 11.0 m/s. Thank you.

A 1.0 kg ball moving at 2 m/s in the +x-direction collides head-on with a 2 kg ball moving at 3 m/s in the –x-direction. The coefficient of restitution is 0.80. Find the velocities of the ball after collision.

A block with mass m 1 =1 kg is released from rest on a frictionless track at a distance h1=2.5 m above the top of a table . it then collides elasticly with a block having same mass m2=1Kg that is at rest on the table. (a) What is the velocity of mass m1 just before collision? (b) What is the velocity of mass 2 just after collision?

A particle of mass m and velocity u collides elastically with a particle of mass M initially at rest. As a result of the collision, the particle of mass m is deflected 90 ° and its speed reduced to uv3. The particle of mass M, recoils with a velocity v forming an angle 0 with the original direction of m. All angles and speeds are observed in the laboratory system. Obtain the value of M as a function of m, v, u, and 0. At what angles are the particles deflected in the center of mass system? М - 2т, v — и/3,0 — п/6; бл — 2п/3,бм — 5л/3 m ans.

A particle of mass m (particle #1) is fired head-on at speed 48 m/s toward another particle of mass 3m (particle #2) which is at rest.  The result of this collision is that #1 comes to a complete stop, and #2 moves forward.  (a) At what speed does particle #2 emerge from the collision?  (b) What fraction of the original kinetic energy is lost during this process?
