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
