Solution:
Since the question of this problem is the car acceleration, the first
step in solving this problem to change the units of the two
velocities to m/s.
and
This problem can be solved using a single formula,
, (U_A_M
5). However, the formula need to be solved for the acceleration.
Substituting the known quantities,
The numerical solution has been finally obtained
using MathCAD:

Solution:
After calculating the acceleration of the car, the time needs by the car
to reach the final velocity can be calculated with the formula
, (U_A_M 3).
Again, the time needs to be solved from the above formula,
