NASA launches a rocket at t=0t=0 seconds. Its height, in meters above sea-level, in terms of time is given by h=−4.9t2+346t+150h=-4.9t2+346t+150. How high is the rocket after 6 seconds? How high was the rocket when it was initially launched?

A person on an assembly line produces P items per day after / days of training, where P(t)= 400 1 + 23e-t . How many days of training will it take for a person to produce 340 items?

Suppose that a baseball is thrown upward with an initial velocity of 110 feet per second (75 miles per hour) and it is released 7 feet above the ground. Its height h after t seconds is given by h = - 16t² + 110t+7. After how many seconds does the baseball reach a maximum height? Estimate this height.

The altitude (in feet) of a rocket t seconds into flight is given by s = t³ - 3t².
