AI Thread Summary
A user seeks assistance with physics problems involving forces, specifically calculating normal force (Fn), frictional force (Ff), and acceleration for a toy sled on a ramp at a 25-degree angle with a mass of 1.0 kg and a coefficient of friction (mu) of 0.25. Additionally, they inquire about determining the coefficient of static friction for a 200.0 kg crate on a 30-degree ramp. Respondents encourage the user to share their work to identify where they are struggling. This collaborative approach aims to enhance understanding of the concepts involved in these calculations. Engaging with the community can provide valuable insights and guidance.

i have some work i need help on any help would be awesome ;)

1. a toy sled is on a ramp with an angle of 25 degrees. It has a mass of 1.0 kg and mu=.25. calculate the Fn, Ff, and acceleration



2. a ramp is at an angle of 30 degrees. a crate on that ramp is 200.0kg. calculate the coeffcient of static friction

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}...
