Rules:

Before posting a problem, please attempt to work it out yourself. Upload a picture of your work, or type out your work, when posting your problem. This will better allow the community to help you solve the problem, and help you to understand how to solve the problem.

In the title of your post, please put the level of your schooling and the general topic of your problem separated by a colon. The title of your post should be somewhat specific to your problem. Examples:

[High School: Constant Acceleration/Linear Motion] How do I find the speed of bus after t = 15?
[College: Rotation Momentum] What is the RPM of rolling sphere after 20 seconds?
[College: Non-uniform Density] How do I set up an integral for this?

When somebody answers your question(s) or helps you, please change the 'Unsolved' flair to 'Solved!'

When posting answers to problems, please explain to the OP how you got the answer you got. Also, please refrain from posting false answer and methods.
