00:01 Suppose h of t is the height in meters of a ball thrown in the air vertically at time t in seconds.
00:07 We are to determine the average height of the ball over the time interval, extending from the ball's release to its return to ground level.
00:19 Now, since we're not given the exact time interval, we need to find it first.
00:26 And the boundaries we're looking at are the ones.
00:30 Which make h a t zero.
00:33 Now if h of t is zero, then 19t minus 4 .9t squared equal zero...
