Projectile Motion and Quadratics

If the function h(t) = -16t² + 160t represents the relationship between the height "h" of an object "t" seconds after it is launched, how many seconds will it take for the object to reach it's maximum height?

The function h(t) = 125t - 5t² represents the height "h" of an object "t" seconds after it was launched into the air from the ground. How many seconds will it take for the object to hit the ground? Find the roots (Input only the number)

In Quadratic Functions, what does "C" represent?

• Total

• Distance

• Time

• The initial value

The function h(t) = -3t² + 12t + 4 models the approximate height "h" of an object "t" seconds after it is launched into the air. How high off the ground was the object launched to begin with? (Only enter the number)

The function h(t) = -2x² + 4x + 30 models the approximate height "h" of an object "t" seconds after it is launched into the air. How long does it take for the object to hit the ground? Find the ROOTS!!! (Only put the number)

The function h(t) = -2x² + 4x + 30 models the approximate height "h" of an object "t" seconds after it is launched into the air. How many seconds did it take for the object to reach its max height? (Only put the number)

A ball is thrown into the air with an upward velocity of 100 ft/s. Its height, h, after t seconds is given by the function
 h = -16t² + 64t + 960.
What is the maximum height?

• 960 feet

• 1008 feet

• 1024 feet

• 1152 feet

An object in launched directly upward at 64 feet per second (ft/s) from a platform 80 feet high. Its height is represented by the equation 
s(t) = –16t² + 64t + 80.
What will be the object's maximum height? 

• 2 ft

• 80 ft

• 144 ft

• 64 ft

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?

• x-intercept

• y -intercept

• vertex

• axis of symmetry

A ball is thrown vertically into the air. Its height in feet after t seconds is given by the equation h(t) = –5t² + 20t, and is graphed below. How high will the ball be after 3 seconds?

• 20 ft

• 15 ft

• 5 ft

• 10 ft
