Jared throws a penny off the top of a building that is 240 feet tall. The distance, in feet, that the penny falls in t second is given by the function s(t)=16t^2. What is the penny's exact velocity when it strikes the ground? What is its acceleration at that point?

The Washington Monument is the world's tallest obelisk at 555 feet. Suppose a penny is dropped from the observation deck from a height of 500 feet. (Let t represent the number of seconds after the penny is dropped.) (a) If the acceleration due to gravity near the surface of the earth is −32 feet per second per second and the velocity of the penny is 0 when it is dropped, write the function for the model for the velocity, v,...
