Question

Chapter 28, Problem 46 An unstable particle is at rest and suddenly breaks up into two fragments. No external forces act on the particle or its fragments. One of the fragments has a velocity of +0.785c and a mass of 2.01 x 10 27 kg, and the other has a mass of 4.70 x 10 27 kg. What is the velocity of the more massive fragment (as a multiple of c)? (Hint: This problem is similar to Example 6 in Chapter 7.)

Answer #1

The particle moves in opposite direction to the fragment According to law of mass conservation of relativistic momentum 1-2 (V2 -= 2 : (0.3459e)ス v,(0.59c) 2 = 0.2980 V4.3557 v, = 0.4 791c

    A uranium-238 atom can break up into a thorium-234atom and a particle called an alpha particle, α-4. The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 × 10−27 kg). When a uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.2 × 105 m/s. Please give the answer in Joules
