Position function and velocity
This is probably an entry-level problem, but I have an exam and need to be clear on this problem.
A ball is thrown straight downward from the roof of a 132-foot building with an initial speed of 52 feet per second. Find the velocity function for the ball and the ball's speed just as it reaches ground level.
I've figured out the that position function is h = -16t(squared) + 52t + 132. I attempted factoring this but the factors I get are decimal numbers [-4(4t(squared)+13t+33)] 16 does not factor evenly into 52 or 132. The factors are needed to continue with this problem. Please help! Thanks.
