Why do you feel qualified to answer advanced physics questions?*

What is the highest level of physics that you have taken in school?*

Provide a step-by-step solution to the problem below:

Mass one, M_1 = 0.25 kg, rests on a ramp which is inclined at an angle of 30 degrees and has a coefficient of kinetic friction of 0.10. Mass one is attached by a massless string which runs up the ramp and over a pulley to mass two, m_2 = 0.20 kg, which hangs off the end of the ramp.

Refer to the image of the two-mass system (link below). Assuming the two-mass system is initially at rest, find the following:

(a) the force of tension in the string,
(b) the acceleration of the system,
(c) find the speed of the system after M_1 has traveled 0.30 meters.

Assume that both masses have more than 0.30 meters of clearance, so at no point does either mass touch the ground. Provide answers with three significant digits.

Answering physics questions for Study.com often involves understanding and using LaTeX to format equations. LaTeX follows simple guidelines, and makes it easy to create beautifully formatted solutions.

For example, we can display an exponent by typing 3x^2. With LaTeX formatting, we can type it as 3x^{2}. The LaTeX formatting will specially display 2 as an exponent, and the caret won’t appear in the output.

Please rewrite the following expression using LaTeX formatting:

5 (square root 3x) + 2x^2 – (3x/2)

Here are a few common LaTeX formatting symbols:
Square root of x: \sqrt{x}
Fraction x over y: \frac{x}{y}
