Physics 12: Acceleration and Distance Problem Solution

In summary, the problem involves a car accelerating from rest to a velocity of 80km/h in 6 seconds. The equations used to solve for the acceleration and distance traveled are a = dv/dt and s=(a/2)*t^2, respectively. To convert from km/h to m/s, simply divide by 3.6. It seems that the online course does not provide any helpful formulas or resources.

Homework Statement



a car accelerates in a straight line from rest ot a velocity of 80km/h in a time of 6s

Homework Equations



what is the acceleration of the car?
how far did the car travel in this time?

The Attempt at a Solution


Now I am trying to convert 80km/h to m/s, so that equals 22.22m/s. I am doing this as an online course and I can't find a formula? Can someone help me please?

1km/hour = 1000m/3600secs = 1/3.6m / s. This means, that to get m/s from km/hour, you just need to divide it by 3.6.
Acceleration a = dv / dt, both of which you know.
And as for how far did the car travel, s=(a/2)*t^2, since it's from resting. Those are the formulas you need.

The course does not provide any reference or study material containing formulas? Sounds like you are wasting your money, if you are paying.
