    Force Slope
AI Thread Summary
To solve for Franz's acceleration while skiing down a 50-degree slope, the mass can be represented as 'm', allowing for the calculation of acceleration in terms of 'm'. The kinetic friction coefficient is 0.05, which plays a crucial role in determining the net force acting on the skier. The forces acting along the slope include gravitational force and friction, which can be expressed mathematically. Ultimately, the mass 'm' cancels out in the calculations, simplifying the process. Understanding these concepts allows for the accurate determination of acceleration without needing the specific mass value.

[SOLVED] Force on a slope

"Franz is skiing in the Alps. He is racing down a steep slope of 50.0 degrees. For waxed skis on snow, we have mu sub k (for kinetic friction)=0.05. What is his acceleration?"

I'm so confused... don't I need his mass to even begin to approach this or am I missing something?
 
Physics news on Phys.org
let m be the mass... get the acceleration in terms of m... (the m's will cancel out when you work out the acceleration).

What is the force acting on the skier along the slope in terms of m...
 
Oh, right. Got it, thank you!
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
