An unstable particle at rest spontaneously breaks into two fragments of unequal mass. The mass of the first fragment is m1 = 2.50 x 10-28 kg, and that of the other is m2 = 1.67 x 10-27 kg. If the speed of m1 is equal to 0.893c after the breakup, where c = 3 x 108 m/s.  What is the final speed of m2

How much work must be done to accelerate an electron to accelerate it from rest to a speed of 0.902c?

An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is equal to 2.60 x 10° -28 kg and that of the heavier fragment is 1.66 × 10° -27 kg. If the lighter fragment has a speed of 0.893c after the breakup, what is the speed of the heavier fragment?

An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is equal to 2.00 x 10-28 kg and that of the heavier fragment is 1.61 x 10-27 kg. If the lighter fragment has a speed of 0.893c after the breakup, what is the speed of the heavier fragment? C

3 J = (the rest energy is 3 c2 A spacecraft moves at a speed of ().8c relative to Earth, and shots a bullet with rest mass of M Joules), and its velocity relative to Earth is in the same direction as the spacecraft. The kinetic energy of the bullet relative to Earth is 5 J. What is the total energy (in Joule) of the bullet relative to the spacecraft?

A particle is moving at  0.75c relative to a lab on Earth. By what percentage is the Newtonian expression for its momentum in error? (The percentage error is the difference between the erroneous and correct values, divided by the correct one).

An unstable particle with a mass equal to 3.34 ✕ 10−27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.981c and −0.861c, respectively. Find the masses of the fragments in kg. (Hint: Conserve both mass–energy and momentum.)

An unstable particle is at rest and suddenly decays intotwo fragments. No external forces act on the particle or itsfragments. One of the fragments has a speed of 0.60c anda mass of 6.67 x 10-27 kg while the other has a mass of 1.67 x10-27 kgWhat is the speed of the less massive fragment?

The muon is an unstable subatomic particle witha mean lifetime of 2.2 μs, and about 10,000 muons reach everysquare meter of the earth's surface a minute. A muon has a linear momentum G, and after some short time it decays into two other elementary particles with masses m1 and m2. The energy Q released during the decay is converted entirely into the kinetic energy of the decay products (i.e., into kinetic energy of m1 and m2). Find linear momenta of decay products. Draw a vector diagram showing a range of momenta decay products can take.
