AI Thread Summary
To calculate the tension and angle in a two-mass pulley system, one must apply Newton's second law, Fr = m*a. Given the masses m1 = 1.0 kg and m2 = 2.0 kg, with an upward force of 6.0 N and a downward acceleration of 5.5 m/s² for m2, the tension in the cord can be derived from the net force acting on m2. The calculations indicate that the tension is significantly higher than the provided values of 218,400 N and 50,400 N, suggesting a need for reevaluation of the approach. The angle β can be determined using trigonometric relationships once the correct tension is established. Accurate calculations are essential for quiz preparation and understanding the mechanics involved.

Homework Statement


In the figure a box of mass m1 1.0kg, on a frictionless inclined surface is connected to another box of mass m2  2.0 kg . The pulley is massless and frictionless. An upward force of magnitude F = 6.0 N acts on m2 , which has a downward acceleration of 5.5 m/s2. What are (a) the tension in the cord and (b) angle  ?


Homework Equations


Fr=m*a

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 .
