A car starts from rest and moves along a straight road with a constant acceleration of 2.45 m/s^2.
a. What is its velocity after 4 seconds?
b. How far does it move from t = 4s to t = 5s?
Expert provides two equations for velocity of a car after 4 seconds, and how far this car moves if it has a constant acceleration of 2.45 m/s^2.
