Question
The height of a ball thrown in the air is a function of the
number of seconds after it is thrown. A 5-foot person
throws it with an initial velocity of 97 ft/sec. The ball is sub-
ject only to acceleration due to gravity.
(A) At what time will the ball reach a height of 100 ft?
(B) What will the ball's height be after 3 seconds?
(C) At what time will the ball hit the ground?
. You can earn $65 in revenue from each sweatshirt sold at a
football game.
(A) How many sweatshirts do you need to sell in order to
earn $50,000 in revenue?
(B) How much revenue will be earned if you sell
215 sweatshirts?
. The concentration (ng/ml) of a drug remaining in the blood-
stream is a function of the amount of time (minutes) since
ingestion of the drug.
(A) What will the concentration of the drug be 45 minutes
after ingestion?
(B) When will the concentration reach a level of 10 ng/ml?
