Question

A stuntman drives a car of mass 885 kg east with a speed of 40 m/s
If the car accelerates at a rate of -3m/s^2, how long will it take the car to go 200 m?

Answer 1

here we have to apply this formula:
\[\Large d = {v_0}t - \frac{1}{2}a{t^2}\]
where \(d=200\), \(v_0=40\), and \(a=-3\).
whereas \(t\) is the requested time.
