Q. A particle of mass M decays into two identical particles each of mass m, where m = 0.4M. Prior to the decay, the particle of mass M has a total energy of 4Mc2 in the laboratory reference frame. The velocities of the decay product are along the direction of motion M. Find the velocities of the decay products in the laboratory reference frame. (Round your answer to three decimal places.)
Billiard ball A of mass = 0.130 moving with speed = 2.80 strikes ball B, initially at rest, of mass = 0.150. Consequently of the collision, ball A is deflected off at an angle of 28.0 with the speed = 2.00.
