PhysicsLAB: Projectiles Released at an Angle

The lesson on Freefall: Projectiles Released at an Angle will help you complete this worksheet. You should also take advantage of the help buttons if you need additional guidance. Remember to have your calculator mode set to "degrees" not "radians."

In each of the following problems, use an H|V Chart to organize your information. You must show all of your calculations on your papers.

Refer to the following information for the next seven questions.

A projectile is released at an angle of 37º above the horizontal at a speed of 15 m/sec.

What are the horizontal and vertical components of its original release velocity?

How much time does the projectile spend rising to its apex?

How high is its apex above the release position?

How fast is it moving as it passes through its apex?

How much total time does it spend in the air?

What is its final range?

What is its resultant impact velocity and angle of impact just as it is about to strike the ground?

Refer to the following information for the next seven questions.

A projectile is released at an angle of 53º above the horizontal at a speed of 15 m/sec.

What are the horizontal and vertical components of its original release velocity?

How much time does the projectile spend rising to its apex?

How high is its apex above the release position?

How fast is it moving as it passes through its apex?

How much total time does it spend in the air?

What is its final range?

What is its resultant impact velocity and angle of impact just as it is about to strike the ground?

Refer to the following information for the next seven questions.

A projectile is released at an angle of 45º above the horizontal at a speed of 15 m/sec.

What are the horizontal and vertical components of its original release velocity?

How much time does the projectile spend rising to its apex?

How high is its apex above the release position?

How fast is it moving as it passes through its apex?

How much total time does it spend in the air?

What is its final range?

What is its resultant impact velocity and angle of impact just as it is about to strike the ground?

Refer to the following information for the next six questions.

Using the results of the three previous question groups, rank each of the following properties of projectiles that when they are released at a common speed but at different angles.

Rank the initial vertical velocity of these three projectiles (37º, 45º, 53º) from greatest to smallest

Rank the time spent in the air of these three projectiles (37º, 45º, 53º) from greatest to smallest.

Rank the initial horizontal velocity of these three projectiles (37º, 45º, 53º) from greatest to smallest.

Rank the range of these three projectiles (37º, 45º, 53º) from greatest to smallest.

Rank the height of apex of these three projectiles (37º, 45º, 53º) from greatest to smallest.

Rank the resultant, impact velocity of these three projectiles (37º, 45º, 53º) from greatest to smallest.
