A small rocket is launched vertically from rest and it accelerates uniformly at 26 m/s² for a period of 13 s, at which point all of its fuel is used. The rocket then continues to travel freely in the vertical direction until it eventually reaches its maximum altitude, after which it falls to earth. Working to 4 significant figures, calculate for the rocket: (a) Its velocity at the instant when all of its fuel is used. m/s (b) Its altitude at the instant when all of its fuel is used. m (c) (i) The time taken for the rocket to slow from the point it runs out of fuel until it reaches maximum altitude. S (ii) The total time taken to reach its maximum altitude S (d) The maximum altitude reached m (e) Its velocity at the instant just prior to impact with the ground. m/s

Question
Transcribed Image Text:A small rocket is launched vertically from rest and it accelerates uniformly at 26 m/s² for a
period of 13 s, at which point all of its fuel is used. The rocket then continues to travel freely
in the vertical direction until it eventually reaches its maximum altitude, after which it falls to
earth.
Working to 4 significant figures, calculate for the rocket:
(a) Its velocity at the instant when all of its fuel is used. m/s
(b) Its altitude at the instant when all of its fuel is used. m
(c)
(i) The time taken for the rocket to slow from the point it runs out of fuel until it reaches
maximum altitude. S
(ii) The total time taken to reach its maximum altitude S
(d) The maximum altitude reached m
(e) Its velocity at the instant just prior to impact with the ground.
