A ball is shot from cannon into the air with an upward velocity of 40 ft/sec. The equation that gives the height (h) of the ball at any time (t) is: h(t) = –16t2 + 40t + 1.5

p. 1- When is the ball at its maximum height?

p.2- Find the maximum height attained by the ball

p.3- What is the ball’s initial height

p.4- What is the ball’s height at 2 seconds

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
