**visoth**, Friday, April 27, 2012 at 4:03pmoh okay here it is sorry about the above;

p(t)= - 16t^2 +64t

14= - 16t^2 + 64t bring 14 to other side and factor or use the equation -b = or minus square root of (b - 4AC)and divide by 2A and you should get what t is

**Damon**, Friday, April 27, 2012 at 5:39pm14= - 16t^2 + 64t

16 t^2 - 64 T + 14 = 0

8 t^2 -32 t + 7 = 0

t = [32 +/-sqrt (1024-224)]/16

= [32 +/- sqrt(800)]/16

= [32 +/- 20sqrt 2]/16

= [ 32 +/- 28.3]/16

= 3.76 on the way down

and

= .231 on the way up
