- An object has a rest mass of 185.0 kg. As the object moves, it is measured that its mass is 192.0 kg. How fast is the object moving?arrow_forwardSuppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 4.0 × 104 kg (about 40 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of N for 22.5 s. The ejected gases have a mass that is small compared to the mass of the spacecraft. You then continue coasting with the rocket engines turned off. Where are you an hour later? (Think about what approximations or simplifying assumptions you made in your analysis.

If m is constant, this becomes F = ma, where a = dv/dt is the acceleration. But in the theory of relativity the mass of a particle varies with v as follows: m= mo/NT- v/c², where mo is the mass of the particle at rest and c is the speed of light. Show that moa F = (1 – v*/c*)/²arrow_forward
