Answer:
Option A
[tex]5 m/s^{2}[/tex]
Explanation:
From fundamental equation of motion
[tex]v^{2}=u^{2}+2as[/tex] where v is the final velocity, u is the initial velocity, a is the acceleration of the body and s is the displacement.
Since the initial velocity is zero
[tex]v^{2}=2as[/tex]
Making acceleration, a the subject of the formula then
[tex]a=\frac {v^{2}}{2s}[/tex]
Substituting 5 m/s for v and 2.5 m for s then
[tex]a=\frac {5^{2}}{2\times 2.5}=5 m/s^{2}[/tex]
