AI Thread Summary
To calculate the tension in the cable of a 1210 kg demolition ball swinging in a vertical circle, one must consider the forces acting on the ball at the lowest point of the swing. The centripetal force required to keep the ball moving in a circular path is provided by the tension in the cable and the weight of the ball. The relevant formulas include the equation for centripetal force and the gravitational force acting on the ball. At the lowest point, the tension in the cable can be determined by adding the gravitational force to the centripetal force. Understanding these forces is essential for accurately calculating the tension in the cable.

A 1210 kg demolition ball swings at the end of a 28.0 m cable on the arc of a vertical circle. At the lowest point of the swing, the ball is moving at a speed of 6.38 m/s. Determine the tension in the cable.

What formula/s would I use to figure this out?
 
Physics news on Phys.org
What is the shape of the arc the ball swings through?

What makes the ball follow that arc?
 
Dimolishing block

At the lowest point centripetal force is equal to the tensition in the sring
 

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 .
