Practice Problems
Uniformly Accelerated Motion
Topics:
On this worksheet you will practice working solving problems by using the
five basic kinematics equations
for uniformly accelerated motion.
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
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 5
Scenario #3:

Question 6
At the point in the stream where the boat in
Question 5
is crossing, the stream is a total of 206 meters wide. If the boat continues maintaining the final velocity it achieves at the end of 9 seconds for the remainder of the trip, how much total time will it need to reach the opposite shore?
34.4 seconds
23.2 seconds

Question 8
Scenario #4:
A go-cart, accelerating down a hill at 2.25 m/sec
^{2}
can travel 69 meters in 7.75 seconds. What was the cart's initial velocity at the top of the hill after a subtle, not so official, push-start?
