a.) the force exerted by the man is found by doing:
Fnormal= mass(gravity)(sin30) - u(mass)(gravity)(cos30)
(The "u" is the coefficient of friction)
b.) the work done by the man is found by using the force we found in the question above and putting it into:
W=Fd
My coeffiecent of friction was 0.40 so my total force was 421.5N
I just put it into W=421.5N(whateverdistanceIgiven)
for example is it was 9cm: (9cm = 0.09m)
W=421.5(0.09m) = 37.935J
c.) the work done by the friction force is solved the exact same way:
Since my coefficient of friction = 0.40 my Force of Friction = 0.41(280kg)(9.8m/s2)(cos30) = 950.5N
Then:
W=Fd = 950.5N(0.09m) = 85.545J
d.) The work done by gravity: First, find force of gravity by: mass(gravity)(sin30) = 1372N, then just plug into W=Fd = 1372(0.09m) = 123.48J
e.) the net work done on the piano = zero
See: 123.48J - 85.545J = 37.935J !

Juris Doctor Law degree.
B-tec honorary degree
A college degree is not required for this field.
what is the different between certificate, diploma, first degree and higher degree programmes?
bachelor's degree and pre med degree.
The grade of an object is the actual incline or slope of a landform or constructed line. The degree of an object is what is used to measure that incline or slope in mathematical equations.
0.08748 miles
Every state below the 36 degree parallel and Missouri. jeffrey: we dont know where 36 degree parallel and missouri
London is on the 44 degree Parallel. 51 degrees north surely!!
no they are parallel therefore they will never intersect
The parallel of zero latitude on the earth is usually referred to as the earth's 'equator'.

right through romania, in the central-eastern part of europe.
How long is the ramp? what degree of incline is it? how long is a piece of string?
parallel. Perpendicular mean 2 lines connect at a 90 degree angle
No because parallel lines never and remain equal distance apart
