Charles is at the top of a ski slope and has compressed himself against a spring that has a spring constant of 3000.N/m(k)that is compressed 3.14 m(??). The snow on the slope has a coefficient of friction of 0.500(μ)and the air resistance is doing 984 J of work against himself(W). The slope has an angle of 30.00(Ɵ) and is 89.0m long(x). Charles has a mass of 30.0Kg(m). Charles reaches a flat horizontal patch of snow that has a coefficient of friction of 0.200 (μ)with the same air resistance as on the slope. How far across the horizontal patch of snow(x)does Charles go?
1) List variables
2) Draw picture with cartesian coordinate system
3) List equations
4) Solve (How far)
We can solve given problem using work energy theorem in two cases .
1) at the downward motion from slip
2)at the horizontal motion i.e on the patch.
We need to find 'x' distance moved by Charles.
