Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time elapsed
Here we have to convert the initial and final velocity of the vehicle into SI units. So we have:
is the initial velocity
is the final velocity
t = 5 s is the time elapsed
Solving for a, we find the acceleration:
