To determine the velocity of the car, we need to know the time for which it has been accelerating. Without that information, we cannot calculate the exact velocity.
However, we can provide a general formula for calculating velocity when acceleration and time are known. The formula is:
v = u + at
Where: v = final velocity u = initial velocity (in this case, the car starts from rest, so u = 0) a = acceleration t = time
Using the given values: u = 0 (starting from rest) a = 6 m/s² (acceleration)
Since we don't have the time, we can't calculate the exact velocity. However, if you provide the time for which the car has been accelerating, we can use the formula to determine the velocity at that specific time.
