Problema Solution

A cannon is fired into the air according to the formula h(t)=-16t^2+1332t

a) what is the height of the cannonball 10 seconds after it is fired?

b) How long before the cannonball hits the ground?

Answer provided by our tutors

a) t =10,  so h = -16(100) +13320 = 11732

 

b)  here h=0 so 16t^2 =1332t  

16t=1332
