Practice Problems
Projectiles Released from Ground Level at an Angle
Topics:
On this worksheet every projectile has a net vertical displacement of s
_{y}
= 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
