Question
A race car leaves the put traveling 10.0mls with uniform acceleration of 10.0 mls (squared). How far has the car gone at the end of 5.00 seconds?

Answer
Helo Eva,

This is a problem for one of the 4 kinematic formulas that you were probably given. The one to choose for this is
d = Vi*t + (1/2)*a*t^2
where the initial velocity, Vi, is zero, the acceleration, a, is 10.0 m/s^2, and time, t, is 5.00 s. Notice that all the given data has 3 digits. That is a clue that 3 significant digits are expected in the answer.

I hope this helps,
Steve

Expertise

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.

Experience

I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
