A ball is thrown straight up from a rooftop 160 feet high with an initial velocity of 48 feet per second. The function s(t) = -16t2 + 48t + 160 describes the ball’s height above the ground, s(t), in feet, t seconds after it is thrown.The ball misses the rooftop on its way down and eventually strikes the ground. Solve, What is the instantaneous velocity of the ball when it hits the ground?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
