Aspaceship at rest relative to a nearby star in interplanetary space has a total mass of 2.60 ✕ 104 kg. its engines fire at t = 0, steadily burning fuel at 76.0 kg/s with an exhaust speed of 4.50 ✕ 103 m/s. calculate the spaceship's acceleration at t = 0, mass at t = 115 s, acceleration at t = 115 s, and speed at t = 115 s, relative to the same nearby star.

(a) acceleration at t = 0 (enter the magnitude. enter your answer in m/s2.)
(b) mass at t = 115 s (enter your answer in kg.)
(c) acceleration at t = 115 s (enter the magnitude. enter your answer in m/s2.)
(d) speed at t = 115 s (enter your answer in m/s.)

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
