AI Thread Summary
The problem involves two masses, m1 and m2, connected by a string over a frictionless pulley, with m1 subjected to a force at an angle. The coefficient of kinetic friction between m1 and the surface is 0.213, which affects the net force acting on m1. To find the upward acceleration of m2, one must first calculate the effective force on m1 considering the angle of the applied force and the frictional force opposing its motion. The acceleration of m1 can then be determined using Newton's second law, ensuring both masses share the same acceleration due to their connection. Understanding the components of the applied force and the impact of friction is crucial for solving the problem.

Mass m1=27.1 kg is on a horizontal surface, connected to mass m2= 7.10 kg by a light string which is hanging. The pulley has negligible mass and no friction. A force of 232.9 N acts on m1 at an angle of 31.7 degrees.

The coefficient of kinetic friction between m1 and the surface is 0.213. Determine the upward acceleration of m2.

What part of the problem is giving you trouble?
 
I no both with have the same acceleration but how do I find the acceleration of the m1 if it's being pulled at an angle?

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}...

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...
