The height (in ft ) of a projectile launched off a cliff over water is given by: h(t) = −16t2 + 555t + 150 where t is the time (in seconds) after launch. (a) What is the initial height of the projectile? Number ft (b) How high does the projectile travel? (round to 2 decimal places) Number ft (c) When does the projectile hit its maximum height? (round to 2 decimal places) after Number seconds
