To find the initial velocity of the rocket, we can use the kinematic equation:
where:-
is the displacement (4000 m),-
is the initial velocity,-
is the acceleration (5.00 m/s²),-
is the time (10.0 seconds).Given:
We need to solve for
:
So, the initial velocity of the rocket must be
.The correct answer is
.
