Answer:
125m/s
Explanation:
Using one of the equations of motion,
v = u + at
where
u = initial velocity of the object
v = final velocity of the object
=> v = 230m/s
a = acceleration of the object
=> a = 42m/[tex]s^{2}[/tex]
t = time taken for the acceleration
=> t = 2.5s
Substituting these values into the equation above gives
230 = u + 42(2.5)
Making u the subject of the formula gives;
u = 230 - 42(2.5)
u = 230 - 105
u = 125m/s
Therefore the initial velocity of the object was 125m/s
Note: The question erroneously has ital velocity rather than initial velocity. This has been corrected as there is no such thing as ital velocity.
