Answer:
(b) 2.40 x kg/s
Explanation:
Given that: Total mass of the rocket = 3.003 x kg
acceleration of the rocket = 36.0 m
speed of the exhausted gases = 4.503 x m/s
Rate at which rocket was initially burning fuel =
But,
time =
=
= 125.0833 s
So that;
Rate at which rocket was initially burning fuel =
= 2400.8001
= 2.40 x kg/s
Therefore, the initial rate at which the rocket burn fuel is 2.40 x kg/s.
B. Newton's second law says that “when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate.”
