Mass A has an initial velocity of 22 m/s in the +x-direction. Mass B is three times more massive than mass A and has an initial velocity of 22 m/s in the –x-direction. If the two masses have an elastic collision, what will be the final velocities of the masses after the collision?

A certain radioactive (parent) nucleus transforms to a different (daughter) nucleus by emitting an electron and a neutrino. The parent was at rest at the origin of an xy coordinate system. The electron moves away from the origin with linear momentum (-7.8 × 10-22 kg m/s) î; the neutrino moves away from the origin with linear momentum (-2.8 × 10-23 kg m/s) j. What are (a) the magnitude and (b) angle (from the +x axis) of the linear momentum of the daughter nucleus? (c) If the daughter nucleus has a mass of 5.6 × 10-26 kg, what is its kinetic energy? (a) Number Units (b) Number i Units (c) Number i Units

A joelshawon is a subatomic particle with a mass of 3.5 G and it is made out of a joelon (mass 1.5 g) and a shawon (mass 2g). A joelon going 7.9 x 10^6 m/s to the east collides with a shawon going 1.2 x 10^6 m/s to the north determine the speed and direction of the resulting joelshawon 

A mass mA= 2.0kg, moving with a velocity vA = (4.0i +5.0j -2.0k) collides with a mass mB = 3.0 kg which is initially at rest. Immediately after the collision, mass mA is observed traveling at velocity vA’ = (-2.0i + 3.0k) m/s. Find the velocity of mass mB after the collision. Assume no external forces act on the two masses.

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 titanium spheres approach each other head-on with the same speed and collide elastically. After the collision, one of the spheres, whose mass is 330 g, remains at rest.  (a) What is the mass of the other sphere?  (b) What is the speed of the two-sphere center of mass if the initial speed of each sphere is 2.9 m/s?

A proton (p) of mass 1.93-u(unified atomic mass units) traveling with a speed 2.22 x 104 m/s of has an elastic head-on collision with a helium (He) nucleus (mHe = 4.00 u) initially at rest. What is the velocity of helium nucleus after the collision?(As mentioned in Chapter 1, 1 u = 1.66 x 10–27 kg but we won’t need this fact.) Assume the collision takes place in nearly empty space.

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 radioactive nucleus initially at rest decays by emitting an electron and a neutrino at right angles to one another.The momentum of the electron is 1.2×10^-22kgm/s and that of the neutrino is 6.4×10^-22kgm/s find the direction and magnitude of the recoil nucleus.If it's mass is 5.8×10^-26kg,deduce the kinetic energy of recoil.
