An object gets a variable acceleration (in m/s2) that changes with time according to the equation: a(t)= 5.0-1.4t 0 < t < 8.0s
1) When is the velocity 6.5 m?
2) What is the maximum velocity?
3) When does the object get maximum velocity?
4) How far has the object travelled when it obtains maximum velocity?
5) What distance does the object move in total from t=0 to t=8.0s?
