I have a few of the problems like the one below to solve this week for homework. If someone could give me some help on this one, It would greatly help in getting me started on knowing how to solve the rest of them. Thanks for any help in advanced. Love this site.
When throwing a softball directly upward from a height of 5 ft with an initial velocity of 50 ft/sec, the height of the softball after t seconds is given by h(t) = -16t^2+50t+5 (until the ball hits the ground).
A) Using the limit definition of the derivative, find the velocity h'(t).
B) when is h'(t) > 0 and when is h'(t) < 0?
