Use the definition finition of the derivative to find f'(x) given f(x) = sqrt(x).
y(t) = -16t^2 + 80t + 96
A ball thrown vertically upward at time t = 0s with initial velocity 80 ft/s and with initial height function in fig 2.1.
a) What is the maximum height attained by the ball?
b) When and with what impact speed does the ball hit the ground?
