Your friend has created a roller coaster capable of speeds up to 62.6 meters per second and says that he is going to make a loop with a 200 meter radius. Will this work? Show your calculations and explain why or why not.

Aball is thrown upward in the air, and its height above the ground after t seconds is h ( t ) = 57 t − 16 t 2 feet. find the time t when the ball will be traveling upward at 14.25 feet per second.
