Projectiles Released from Ground Level at an Angle


Topics: On this worksheet every projectile has a net vertical displacement of sy = 0; that is, the projectiles launch and land at the same height.

Page Directions The numerical values in this worksheet are randomly generated allowing students the opportunity to conveniently practice, and drill, common situations.

Before beginning any given worksheet, please look over all of the questions and make sure that there are no duplicate answers shown for the same question. If duplicates are present simply refresh the page until every answer is unique.

In order to check an answer (even when you are just starting the worksheet on Question 1) it is necessary to omit any questions that you have not answered. Once you start submitting answers, the page may be checked as many times as necesasary without changing the randomized answers. Relevant scoring will be provided at the top of the page only when you answer all of the questions on your original submission.






Question 1  A football is kicked so that is has a hang time of 3.2 seconds and hits the ground 31 meters down the field, what was the velocity of the football when it was kicked?
Question 2  A cannon is fired on flat ground so that its shell comes back to the ground 465 meters away. If the cannon ball is in the air for only 6.4 seconds, with what velocity was it fired?
Question 3  A softball is struck up into the air with a hang time of 5.9 sec and is caught 10.3 meters away. What was the velocity of the softball just as it was struck by the bat?
Question 4  A catapult launches its mass at a speed of 33.3 m/sec at an angle of 31 degrees. How long will the mass stay in the air if its release-height and landing-height are the same?
Question 5  An arrow is shot up into the air at 16.7 m/sec at an angle of 49 degrees. What is the range of the arrow if its release-height and impact-height are the same?
