How long would it take for a ball dropped from the top of a 64 foot building to hit the ground? Round your answer to 2 decimal places
Answer provided by our tutors
The height h of the ball after t seconds is given by the quadratic equation:
h=-16t^2+64
we need to find t, t>o such that h = 0 that is
-16t^2+64 = 0
by solving we find:
t = 2 sec
