The maximum height the cannonball reached is 264m
Maximum height of an object
Given the equation of the height expressed as h(t)= -16t^2+144t
At maximum height, thee veloicity of the object is zero, hence;
- v(t) = -32t + 144
If the velocity of the object is zero, hence:
-32t + 144 =0
32t = 144
t = 4.5secs
h(4.5) = -16(4.5)^2 + 144(4.5)
h(4.5) = -384 + 648
g(4.5) = 264m
Hence the maximum height the cannonball reached is 264m
