Math 1 - Chapter 8.7 Projectile Motion

Label the quadratic function.

What algebraic term are you solving for if the word problem is: Members of the math club launch a model rocket from ground level with an initial velocity of 96 ft/sec. This can be modeled with the function h(t) = -16t² + 96t. When does the rocket land?

In Projectile Motion Quadratic Word Problems, what does the x-value always represent?

When working with Quadratic Projectile problems, what does the y-axis always represent?

Click on the dot where the vertex of the parabola is.

A toy rocket launched from a platform that is 48 feet high. The rocket's height above the ground is modeled by $$h=-16t^2+32t+48$$ , where h is height in feet and t is time in seconds. Find the time it takes the rocket to reach the ground.

(a) What is the maximum height ​ (a)   feet.

(b) When will the rocket reach its maximum height. ​ (b)   second.

(c) How long is the rocket in the air ​ (c)   second.

Members of the math club launch a model rocket from ground level with an initial velocity of 96 ft/sec. This can be modeled with the function h(t) = -16t² + 96t. When does the maximum height occur?
