A spaceship at rest relative to a nearby star in interplanetary space has a total mass of 2.00 ? 104 kg. Its engines fire at t = 0,
steadily burning fuel at 79.3 kg/s with an exhaust speed of 4.50 ? 103 m/s. Calculate the spaceship's acceleration at t = 0,
mass at t = 135 s,
acceleration at t = 135 s,
and speed at t = 135 s,
relative to the same nearby star.
(a)
acceleration at t = 0
(Enter the magnitude. Enter your answer in m/s2.)
m/s2
(b)
mass at t = 135 s
(Enter your answer in kg.)
kg
(c)
acceleration at t = 135 s
(Enter the magnitude. Enter your answer in m/s2.)
m/s2
(d)
speed at t = 135 s
(Enter your answer in m/s.)
m/s
