Question

A particle of mass m moves with a speed c/2. Calculate its mass , momentum total energy and kinetic enedgy

Answer 1

mass = m , velocity = (3*10^8)/2  (c/2)

mass = m

momentum = 1/2*m*3*10^8

kinetic energy = 1/8*m*3*10^16

Answer 2

Answer: knowing some relations would be just enough to solve this problem..
