Question

A group of engineering students construct a potato cannaon. The hight, h metres, of a potato t seconds after it is shot from the cannon that is on the roof of a building is modelled by the equation.
h= -5(t-2)^2 + 45

a) how high is the potato after 1 s?
b)when does the potato reach its maximum height?
what is the height ?
c) How long is the potato in the air? A group of engineering students construct a potato cannaon. The hight, h metres, of a potato t seconds after it is shot from the cannon that is on the roof of a building is modelled by the equation.
