Two particles with masses 2m and 8m are moving toward each other along the x axis with the same initial speeds v. 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 v,. 1.856 Your response differs from the correct answer by more than 10%. Double check your calculations. x v, .866 Your response four-digit accuracy to minimize roundoff error. x v, particle 2m particle 8m s within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least

In the figure, projectile particle 1 is an alpha particle and target particle 2 is an oxygen nucleus. The alpha particle is scattered at angle 0₁ = 72.2° and the oxygen nucleus recoils with speed 1.60 x 105 m/s and at angle 0₂ = 47.0°. In atomic mass units, the mass of the alpha particle is 4.00 u and the mass of the oxygen nucleus is 16.0 u. What are the (a) final and (b) initial speeds of the alpha particle? m₁ Đ Vli m₂ 0₁ Vof x

Two objects of masses m1 = 2.0 kg and m2 = 1.3 kg moving towards each other with speeds of 2.2 m/s and 3.1 m/s, respectively, collide inelastically. Calculate the amount of kinetic energy lost in this collision, in joules.

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?

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.

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?

Car A and Car B are traveling in the same direction (call it i^), with B behind A, and initial speeds vA=5.6 m/s, and vB = 6 m/s. The cars have identical mass m=103 kg, and they experience an elastic collision.  Now, this collision is observed by a third person traveling in a car with constant velocity v=6 m/s, traveling in the same direction as the two cars.  From the point of view of this person calculate the following:  1)The initial momentum of car A. 2)The initial momentum of car B. 3)The final momentum of car A (you might want to first calculate the final velocity of car A relative to the ground). 4)The final momentum of car B (you might want to first calculate the final velocity of car B relative to the ground). 5)The total final kinetic energy: 6)The total final kinetic energy as measured from the ground. 7)Based on the previous answers and your calculations of the total initial kinetic energy, does the third person conclude that the collision is:

A radioactive nucleus at rest decays into a second nucleus, an electron, and a neutrino. The electron and neutrino are emitted at right angles and have momenta of pe = 9.26×10−23 kg⋅m/s and pν = 5.98×10−23 kg⋅m/s , respectively.   Determine the magnitude of the momentum of the second (recoiling) nucleus. Determine the angle between the momentum of the electron and the momentum of the second (recoiling) nucleus.
