Question

The equation for a projectile's height versus time is .

h(t)= -16t^2+Vot+ho

A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 110 feet per second. What is the maximum height, in feet, the ball will attain?

Round to the nearest hundredth.

Answer 1

I think it should be 1134 feet. Since it wants a max you take the derivative making it 0=-32*t+Vo. If you use -32 for the acceleration of gravity that's what you would get. Hope that's right.

Answer 2

thank you

Answer 3

no problem
