    Plane
AI Thread Summary
The discussion centers on solving a physics problem involving an inclined plane with a block resting on it. The plane is accelerating, and the goal is to determine the minimum acceleration required for the block to slide down. The user has attempted various equations, including applying Newton's second law, but has not found a solution. Key equations mentioned involve forces acting on the block, including friction and gravitational components. Assistance is sought to correctly derive the acceleration needed for the block to overcome static friction and slide down the incline.

this is another post, but i just want to post it in this room and see if ANYONE knows how to solve this:
I've tried everything, now I'm getting depererate

An inclined plane that makes an angle of 28° to the horizontal is mounted on wheels. A small block of mass m = 1.2 kg rests on the plane, held there by a coefficient of static friction µ = 0.73.


The plane is accelerating to the right. What is the minimum acceleration in order that the block slides down the plane?

Any help would be great !

Apply Newton's 2nd Law and solve for a.

The 0 degrees with the horizontal system of coordinates will be the easier one.
 
i tried literally everything, would anyone please help me solve it? lol...

i came up with the following, after lots of equation, i used it to solve for a, didn't work either

g sin (theta) - mu (a sin (theta) + g cos (theta) ) = a cos (theta)
 
Well, with the coordinate system set as i said above.

\sum F_{x} = ma = - n \sin \theta + F_{f} \cos \theta

\sum F_{y} = 0 = F_{friction} \sin \theta + n \cos \theta - mg

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}...
