Aball is thrown upward in the air, and its height above the ground after t seconds is h ( t ) = 76 ⋅ t − 16 t 2 feet. find the time t when the ball will be traveling upward at 19 feet per second.

t = 1.78 s

Explanation:

As we know that the height of the ball from ground is given as a function of time

now we know that rate of change in the position of ball is known as velocity of the ball

it is given as

now we have to find the time at which the velocity of ball is 19 ft/s in upward direction so we have

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
