An acrobat springs from a trampoline that is 2 feet off the floor with an initial upward velocity of 24 feet per second. What is the model of this function?

• h(t)=-16t²+2t+24

• h(t)=-16t²+24t+2

• h(t)=24t²+2t-16

When playing basketball, Frank shoots an air-ball. The height of the basketball at any given time is modeled by the function h(t)=-16t²+32t+9. What is the maximum height the ball will reach?

• 32 ft

• 0 ft

• 9 ft

• 25 ft

A diver is standing on a platform above the pool. He jumps from the platform with an initial upward velocity of 8 ft/s. Use the formula h(t) = −16t² + 8t + 24, where h is his height above the water, t is the time, v is his starting upward velocity, and s is his starting height. How high is the platform?

• .25 ft

• 24 ft

• 25 ft

• 8 ft

A ball is thrown into the air with an initial velocity of 64 ft/s. Its height, h, after t seconds is given by the function

h = -16t² + 64t + 960.

What will the height be when the ball hits the ground?

• 0 ft

• 64 ft

• 960 ft

• 1024 ft
