In this lecture we will explore further the velocity and displacement of an object under constant acceleration. We will deduce some simple relationships and work several problems.
Several examples follow.
Find the initial speed and the acceleration. A person in an apartment below, who just happens to have a stopwatch handy, notices that it takes 0.2 sec for the pot to fall past his window, which is 4 m high. Ball A is dropped from the top of a building at the same instant that ball B is thrown vertically upward from the ground.
