12. [3/4 Points] DETAILS A spaceship at rest relative to a nearby star in interplanetary space has a total mass of 2.60 x 10 kg. Its engines fire at t=0, steadily burning fuel at 72.6 kg/s with an exhaust speed of 4.50 x 10 m/s. Calculate the spaceship's acceleration at t-o, mass ate=115 s, acceleration at t-115 s, and speed at t-115 s, relative to the same nearby star. HINT (a) acceleration at r0(Enter the magnitude. Enter your answer in m/s²) 12.57 m/s² (b) massat-115 (Enter your answer in kg) (c) acceleration at 115s (Enter the magnitude. Enter your answer in m/s².) 18.61 m/s² (d) speed at t-115 # (Enter your answer in m/s.) x m/s
