AI Thread Summary
To calculate the work done on a 15.0N object moved 3.00m with a 60.0N force, the relevant force is the 60.0N applied horizontally. The weight of the object, 15.0N, is not used in this calculation since it acts perpendicular to the direction of motion and does no work. Work is calculated as the product of force and distance in the direction of the force. Therefore, the work done is 60.0N multiplied by 3.00m. Understanding the direction of forces is crucial in determining the correct force to use for work calculations.

A 15.0N object is moved horizontally 3.00m across a level floor using a horizontal force of 60.0N. how much work is done on this object?

I am not sure should I use 15.0N or 60.0N to find the work

Thanks for helping!

I think you'd use 60.0 N.
15.0N is just the mass in kg times gravity.
 
Remember forces that are perpendicular to the direction of motion do no work. Here the 15N Weight is perpendicular to the direction of motion, whereas the 60N force is parallel to the direction of motion.
 

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 .

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 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
