Question

Consider inertial observer A. Observer A measures the acceleration of spaceship A. Observer A is aboard a ship that sees Spaceship A moving with a velocity of +0.4c, and accelerating at 3.6 m/s 2 The mass of Spaceship A is 2 × 10^5 kg. Calculate the thrust force (in Newtons) of the Spaceship A’s engines according to observer A, both using the classical definition of force and the relativistic definition..
