Question

A race car completes the final lap of a race on a 2-kilometer circular track. At the start of the lap, it crosses the line at 60 meters/second. It completes the lap 28.57 seconds later, crossing the line at 85 meters/second. Calculate the displacement and average acceleration of the car within the span of 12 seconds.

Answer 1

Answer 2

The average acceleration is going to be the difference in velocity divided by time.

Displacement will be \(x(t) = v_0t + \frac{1}{2}a t^2\) where \(v_0\) is the initial velocity.
