Answer #1

Particle decay process: a 0.60 0.6c 0.6c Particle Collision: m 0.66 0.6c mo

B) Change is Mass:

          When a particle travels in high velocity it exhibits a relativistic effect like length contraction, and time dilation, as well as the mass of the particle, is also changed from its rest mass.

                   In the first process where rest particle decay into two equal masses travels in the opposite direction with an equal velocity of 0.6c

So, the relativistic mass of this particle

massrelativistic = For the first process m mo =

me=2m mo? 11-V47c2 mo =- mo = _2m 7.60.60)/2 2m m, = 0.8 m, = 2.5m Change in mass Am = Total mass of Parent- total mass of da

    Initially a 4kg mass and a 2kg mass are at rest on a friction free surface held together by a string. Between these two masses is a spring compressed by 0.1 m. At t= 0 , the string is cut and the two masses allowed to fly apart. When the masses are far apart, the velocity of the 2kg mass is 2m/s. 1) What is the velocity of the 4kg mass?? 2) Is momentum conserved in this process, i.e is...

    An object of mass 4m is initially at rest. It breaks into three parts, two of mass m and one of mass 2m. After the explosion, one of the object of mass m moves along the positive y-axis with a speed of 10 m/s and the other one of mass m moves along the negative x-axis. Find the magnitude and the direction of the velocity of 2m after the explosion.
