Question

The mass m of a body moving with a velocity v is given by m= ., where m = rest mass of body = 10 kg and c = speed of light = 3 x 10 m/s. Find the value of mat v = 3 x 10 m/s. (1) 9.05 kg 2) 10.05 kg (3) 8.5 kg (4) 11.5 kg.

• The mass m of a body moving with a velocity v is given by m=m_(0)/sqrt(1-v^(2)/c^(2)) where m_(0) = rest mass of body =10 kg and c = speed of light =3xx10^(8) m//s.
