Edit: I'll fix the symbols once I figure out how to do them properly. Sorry about that.(adsbygoogle = window.adsbygoogle || []).push({});

Is there a tutorial ob how to use the math symbols? I can't find one anywhere.

1. The problem statement, all variables and given/known data

A man pushes a box up an inclined plane making an angle of 30 degrees with the horizontal. The mass of the box is 60kg, and the coefficient of kinetic friction between the box and the ramp is 0.45. How much work must the man do to push the box to a height of 2.5m at constant speed. Assume that the man pushes the box in a direction parallel to the surface of the ramp.

Angle = 30 degrees

Mass = 60kg

[tex][tex]\mu[/tex]_{}k[/tex]

Height = 2.5m

2. Relevant equations

1/2m[tex]^_{1}v{2}[/tex] + mg[tex]y{1}[/tex] = 1/2m[tex]^{2}v{2}[/tex] + mg[tex]{2}[/tex]

[tex]\Delta[/tex]K = W

K = 1/2 mv^2

3. The attempt at a solution

I worked on this sort of aimlessly for about 45 minutes. I'm honestly embarrassed to post anything because I am teaching myself this material and have no idea what I'm doing; however, I'll post something if necessary
