A car travels in a straight line. Taking: 15 seconds to travel 220m And 10 seconds to travel the next 220m. What is the acceleration. (Acceleration is constant)
I have tried using motion equations to simultaneously solve the question, but seem to be going round in circles.
Any guidance is much appreciated.
Try solving $s=\frac{at^2}{2}+v_0t$ for $a, v_0$ with $s=220, t=15$ and with $s=440, t=25$. That gives you two linear equations in two unknowns.
