Problema Solution
A football player kicks a football in a way that its height is given by d(t)=-16t^+24t+2. What is the maximum height reached by the football? What is the hang time of the football?
Answer provided by our tutors
d(t)=-16t^+24t+2.
d'(t) = -32t+24
for maxima d'(t) =0
then
-31t+24 = 0
32t = 24
t = 24/32
t = 6/8
t = 3/4
d(3/4)=
