Problema Solution
The height of an object thrown upward with an initial velocity of 32 feet per second is given by the formula h = −16t2 + 32t, where t is the time in seconds. How long will it take the object to reach a height of 16 feet?
Answer provided by our tutors
h = −16t^2 + 32t
we need to find t>0 such that h = 16 ft
−16t^2 + 32t = 16
by solving we find
t = 1 sec
