A police officer on a mountain bike is cruising at a speed of 3.50m/s, when he sees a wanted

criminal, standing on a corner, 75m ahead of him. If the police officer accelerates at a rate of
2.00m/s^2, how much time will he take to reach the corner?

vf² = vo²+2ad

vf=vo+at

vf²=3.5²+2.2.75

vf=vo+at

17.67 = 3.5 +2t

t=7.085 s
