Question

A rock is thrown off of a 100 foot cliff with an upward velocity of 50 m/s. As a result its height after t seconds is given by the formula:
h(t) = 100+ 50t - 5t²
What is its height after 3 seconds?
What is its velocity after 3 seconds?
(Positive velocity means it is on the way up, negative velocity means it is on the way down.)
