Answer to Question #164307 in Physics for Nicole

Question #164307

A car accelerates uniformly, from rest, at 2 m.s for 20s. it then travels at constant velocity for 60 s and finally brakes uniformly to rest in 8 s. Calculate the total distance covered.

Expert's answer

"v=at_1=(2)(20)=40\\frac{m}{s}\\\\s=0.5(2)(20)^2+(40)(60)+0.5(8)(40)=2960\\ m"
