An unstable particle at rest spontaneously breaks into two fragments of unequal mass. The mass of the first fragment is 3.00 10-28 kg, and that of the other is 1.86 10-27 kg. If the lighter fragment has a speed of 0.844c after the breakup, what is the speed of the heavier fragment

Speed = m/s

Explanation: Like in classical physics, when external net force is zero, relativistic momentum is conserved, i.e.:

Relativistic momentum is calculated as:

p =

where:

m is rest mass

u is velocity relative to an observer

c is light speed, which is constant (c=m/s)

Initial momentum is zero, then:

= 0

= 0

To find speed of the heavier fragment:

The speed of the heavier fragment is m/s.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
