The device applies a time-dependent force so that the rate of change of the lab-frame magnitude of a pellet’s 3-vector momentum is dp/dt = bt, where b is a positive constant. after a lab-frame time t has elapsed the force drops to zero, and stays zero. what is a pellet’s lorentz factor γ = 1 p 1 − v 2/c2 after the accelerating force drops to zero?
