We can use the equation of motion:
×
Since the acceleration and velocity are both downward, we will regard the downhill direction as positive.
Solving the quadratic:
Negative time is not possible so the second value is discarded. Time taken seconds
A larger span of time can be broken up into several shorter, equal-length segments. These are referred to as time periods. Consider the scenario where you wished to gauge a car's speed over an hour-long trip. You could break up an hour into ten-minute segments. A time interval is the length of time between two specific points in time.
For example, "The time difference between 3:00 and 4:00 is 1 hour."
