Question

What is the terminal speed for an 84.0kg skier going down a 37.0degree snow-covered slope on wooden skis μk= 0.060? Assume that the skier is 1.80m tall and 0.300m wide.

Answer 1

Okay, here is a solution. Not sure if it's the best one, but it seems to work.

D = drag force
D = (1/4)Av^2 v is terminal velocity
A = 1.80m * 0.300m

F(net) = D since there is no acceleration

m*g*sinè - ì(kinetic)*m*g*cosè = (1/4)Av^2

solve for v (your terminal velocity)

Your answer should be in the high 50s

Answer 2

those funky è letters are supposed to be theta. The funky ì is mu.
