1.A ball is thrown downward from a window in building. Position at time t in secondsĀ is s=16t^2+32t, where s is in feet. How long (to nearest tenth) take the ball to fall 107 feet?

1.A ball is thrown downward from a window in building. Position at time t
in seconds is s=16t^2+32t, where s is in feet. How long (to nearest
tenth) take the ball to fall 107 feet?

The equation is:

16t^2 + 32t = 107

16t^2 + 32t - 107 = 0

Find t using the quadratic formula:
a = 16; b = 32; c = -107
