Question:

You observe a lead brick with a rest mass of 16 kg. What is its apparent mass if it is moving away from you at 0.85c? The speed of light is 3 × 108 m/s. Answer in units of kg. (part 2 of 2) What is its apparent mass if you are moving toward it at −0.85c? Answer in units of kg.


Answers

mass is given by=m/sqrt(1-(v/c)^2)

so both for 0.85c and -0.85 apparent mass will be same given by

apparent mass=30.37 kg
