5. Suppose a tomato is thrown vertically from the edge of a cliff so that its height s in feet above ground after t seconds is given by s(t) = -16t2 + 64t + 32. Determine the velocity of the tomato at the moment it reaches its maximum height. [A] 2 feet/second [B] 16 feet/second [C] 0 feet/second [D] -2 feet/second [E] -16 feet/second 6. Find F'(0) if F(0) = ecos(40) [A] 4e cos(40) [B] -4 sin(40) e cos(40) [C] sin (40) e cos(40) [D], 4 cos (40) e-sin(40) [E] -cos(40) e cos(40)-1
