Alg1B Projectile Motion Practice

Front

What is the formula for the height of an object in projectile motion?

Back

h(t) = -16t² + vt + h₀, where v is the initial velocity and h₀ is the initial height.

Front

What does the variable 't' represent in the projectile motion formula?

Back

The variable 't' represents time in seconds.

Front

How do you find the maximum height of a projectile?

Back

The maximum height occurs at t = -b/(2a) in the quadratic equation h(t) = at² + bt + c.

Front

What is the significance of the coefficient -16 in the height formula?

Back

The coefficient -16 represents the acceleration due to gravity in feet per second squared.

Front

If a ball is thrown with an initial velocity of 100 ft/s, what is the height after 2 seconds?

Back

h(2) = -16(2)² + 100(2) + h₀.

Front

What is the initial height if the height function is h(t) = -16t² + 100t + 5?

Back

The initial height is 5 feet.

Front

How do you determine when a projectile hits the ground?

Back

Set h(t) = 0 and solve for t.

Front

What is the maximum height of a projectile thrown with an initial velocity of 100 ft/s?

Back

Maximum height can be found using t = -b/(2a) in the height function.

Front

What does the term 'initial velocity' mean in projectile motion?

Back

Initial velocity is the speed at which the object is thrown or launched.

Front

How can you calculate the time it takes for a projectile to hit the ground?

Back

Use the quadratic formula to solve for t in the equation h(t) = 0.
