**Steve**, Thursday, March 29, 2012 at 11:54amthis is just a standard acceleration problem.

s = 1/2 at^2

16 = 1/2 * 2 * t^2

16=t^2

t=4

so, in 4 min the house will be 16' tall, and he will be (briefly) safe.

**Steve**, Thursday, March 29, 2012 at 11:56amnow, if you want to use your calculus, let f(t) be the height of the house after t minutes.

f ''(t) = 2

f '(t) = 2t + c

f '(0) = 0 means c=0 and

f '(t) = 2t

f(t) = t^2+c

f(0) = 0 means c=0, so

f(t) = t^2

16 = t^2

t=4
