We can use the equations of motion to solve this question. These equations relate, initial velocity (u), final velocity (v), distance traveled (s), time taken (t) and acceleration (a), as:
Here, the car starts from rest, hence u = 0. The acceleration of the car, a = 5.48 m/s^2 and the distance traveled is, s = 115 m.
Using the third equation from above,
solving the equation, we get, v = 35.5 m/s
Given the acceleration and distance traveled by the car, we can use the second equation to determine the time of travel as:
Thus, we can use the equations of motion to determine the unknown variables.
Hope this helps.
