A neutron collides elastically with a helium nucleus (at rest
initially) whose mass is four times that of the neutron. The helium
nucleus is observed to rebound at an angle x = 43° from the
neutron's initial direction. The neutron's initial speed is
6.4*10^5 m/s. Determine the angle at which the neutron rebounds,
measured from its initial direction.
a) Incorrect: Your answer is incorrect. 73.96°
b) What is the speed of the neutron after the collision?
Incorrect: Your answer is...

A proton collides elastically with another proton that is
initially at rest. The incoming proton has an initial speed of
4.00e5 m/s. The incoming proton has an initial speed of 4.00e5 m/s
and makes a glancing collision with the second proton (at close
separations, the protons exert a repulsive electrostatic force on
each other). After the collision, one proton moves off at an angle
of 30.0 degrees to the original direction of motion and the second
deflects at an angle...

One electron collides elastically with a second electron
initially at rest. After the collision, the radii of their
trajectories are 1.00 cm and 2.50cm. The trajectories are
perpendicular to a uniform magnetic field of magnitude 0.0380 T.
Determine the energy (in keV) of the incident electron.

An atomic nucleus of mass m traveling with speed v collides
elastically with a target particle of mass 2m (initially at rest)
and is scattered at 90°. (a) At what angle does the target particle
move after the collision? (b) What are the final speeds of the two
particles? (c) What fraction of the initial kinetic energy is
transferred to the target particle?

An alpha particle is a nucleus of helium. It has twice the
charge and four times the mass of the proton. When they were very
far away from each other, but headed toward directly each other, a
proton and an alpha particle each had an initial speed of 0.005c,
where c is the speed of light. What is their distance of closest
approach? Hint: There are two conserved quantities. Make use of
both of them. (c = 3.00 × 108...

An alpha particle is a nucleus of helium. It has twice the
charge and four times the mass of the proton. When they were very
far away from each other, but headed toward directly each other, a
proton and an alpha particle each had an initial speed of
4.1×10-3 c, where c is the speed of light. What is their
distance of closest approach? There are two conserved quantities.
Make use of both of them. (c = 3.00 × 10^8...

Compton Scattering.A photon of wavelength λcollides elastically
with a free electron (initially at rest) of mass m. If the photon
scatters at an angle φfrom its original direction of travel, use
conservation of relativistic linear momentum and conservation of
relativistic energy to derive a mathematical expression for the
scattered photon’s wavelength λ’.

A 100 g ball collides elastically with a 300 g ball that is at
rest. If the 100 g ball was traveling in the positive x-direction
at 5 m/s before the collision, what are the velocities of the two
balls after the collision?

An unstable nucleus with a mass of 16.3 × 10−27 kg initially at
rest disintegrates into three particles. One of the particles, of
mass 4.9 × 10−27 kg, moves along the positive yaxis with a speed of
4.5 × 106 m/s. Another particle, of mass 8.7 × 10−27 kg, moves
along the positive x-axis with a speed of 3.4 × 106 m/s.
a) Find the speed of the third particle. Answer in units of
m/s.
b) At what angle does...
