Projectile Motion

An object in free fall is also called

• gravity

• projectile motion

• projectile

• tide

• 10 seconds

• 64 seconds

• 960 seconds

• 2 seconds

The height of an object thrown into the air can be modeled by the formula h(t) = -16t² + 70t + 95, where h(t) is in feet after t seconds.
What is the height of the object after 5 seconds?

• 95 feet
• 45 feet
• 70 feet
• 171.56 feet

Charlie shoots a basketball from a height of 6 feet with an initial upward velocity of 18 feet per second. It follows the path h(t) = -16t² + 18t + 6. How long will it take the ball to reach the maximum height?

• 0.6 seconds

• 11 seconds

• 6 second

• this graph has a minimum

Joe Mauer hits a fly ball. You can track the height of the ball using the equation: h(t) = -16t² + 140t + 2. What is the starting height of the ball?

• -16 feet

• 140 feet

• 2 feet

• 0 feet

The pathway of an arrow can be represented by the equation h = -16t² + 80t + 25, where h is the height in feet and t is the time in seconds. What is the maximum height?

• h = 125 feet

• h = 80 feet

• h = 95 feet

• h = 140 feet

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.
When did the ball hit the ground?

• 10 seconds
• 2 seconds
• 5 seconds
• 7 seconds
