AI Thread Summary
In a frictionless pulley system with masses m1 = 5.00 kg and m2 = 8.00 kg, the acceleration can be calculated using Newton's second law. The net force acting on the system is determined by the difference in weights of the two masses. The formula for acceleration (a) is derived from the equation a = (m2 - m1)g / (m1 + m2), where g is the acceleration due to gravity. Substituting the given values results in the acceleration of the system. This approach effectively solves for the acceleration in a frictionless environment.

The system shown in the figure is accelerating. Asume that there is no friction anywhere in the system and that the mass of the string can be neglected. The values of the masses are:

m1=5.00 kg
m2=8.00 kg

Determine the acceleration of the system.

Figure and work done so far shown here:

Where do I go from here? How do I solve for the acceleration?

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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
