Unit 1.3 Projectile Motion Lesson

A projectile is launched at 68.0° above the horizontal and at a speed of 55 m/s. How long will it take the projectile to reach maximum height?

A projectile is launched at 68.0° above the horizontal and at a speed of 55 m/s. What is the maximum height reached by the projectile?

A projectile is launched at 68.0° above the horizontal and at a speed of 55 m/s. What is the projectile's x-component of velocity at the maximum height?

A projectile is launched at 68.0° above the horizontal and at a speed of 55 m/s. What is the horizontal displacement at maximum height?

If  $$h\left(t\right)=-16t^2+84t+140$$  ,  what is the value used for gravity?

If  $$h\left(t\right)=-16t^2+84t+140$$  ,  what is the initial velocity?

If  $$h\left(t\right)=-16t^2+84t+140$$  ,  what is the initial height?

If  $$h\left(t\right)=-4.9t^2+18t+43$$  ,  what is the value used for gravity?

If  $$h\left(t\right)=-4.9t^2+18t+43$$  ,  what is the initial velocity?

If  $$h\left(t\right)=-4.9t^2+18t+43$$  ,  what is the initial height?

Write the function that models the path of an object thrown from a height of 12 feet with an intial velocity of 19 feet/sec.

Write the function that models the path of an object thrown from a height of 25 meters with an initial velocity of 40 meters/sec.

An object's path is modeled by: $$h\left(t\right)=-16t^2+150t+100$$   HOW LONG until max height?
