If a ball is thrown upward from a building 30 m tall and the ball has a vertical velocity of 25 m/s, then its approximate height above the ground t seconds later is given by h(t) = 30 + 25t - 5t^2 a
If a ball is thrown upward from a building 30 m tall and the ball has a vertical velocity of 25 m/s, then its approximate height above the ground t seconds later is given by h(t) = 30 + 25t - 5t^2 a. After how many seconds does the ball hit the ground? b. What is the domain of h? c. How high does the ball go?

1. Recall the following scenario from a class activity: A ba is thrown (from the ground) to a height of 10 feet. It then falls and bounces repeatedly. After each bounce, it rises to of the previous height (a) Express the total vertical distance the ball travels until it stops (going up and down on each bounce) as a geometric series and compute its value using the short-cut formula for geometric series. Make sure to justify the geometric series you...

A student with a third floor dormitory window 32 feet off the ground tosses a water balloon straight up in the air with an initial velocity of 16 feet per second. It turns out that the instantaneous velocity of the water balloon is given by the velocity function v(t) = -32t + 16, where v is measured in feet per second and t is measured in seconds. Let s(t) represent the height of the water balloon above the ground at time...
