AI Thread Summary
To resolve friction problems, begin by creating a free-body diagram that clearly labels all acting forces. Apply Newton's second law to both the x and y directions to analyze the forces at play. For the x-direction, calculate the horizontal force components, while for the y-direction, account for vertical force components. This structured approach helps in understanding the dynamics involved. Accurate calculations and clear diagrams are essential for effective problem-solving in physics.

Start by drawing a free-body diagram, labelling all forces, and writing out Newton's second law for both the x and y directions.

Fxdirection=42cos30+[(12kg)(9.8m/s2)]
Fydirection=42sin30+[(12kg)(9.8m/s2)]


something like that?
 
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}...
