Solving Kinetic Energy Lost in Collision: Help Needed

AI Thread Summary
The discussion centers on calculating the kinetic energy lost during a collision between two particles with different masses and velocities. A 78g particle traveling at 39m/s collides with a 160g particle moving at 33m/s. Participants seek guidance on the equations needed to determine the kinetic energy loss, with suggestions to refer to a specific physics resource for assistance. There is a request for a step-by-step explanation due to confusion over the calculations. The conversation emphasizes the importance of understanding momentum and energy concepts in solving the problem.

A 78g particle moving with an initial speed of 39m/s in the positive x direction strikes and sticks to a 160g particle moving with 33m/s in the positive y direction.

How much kinetic energy is lost in this collision? Answer in units of J.


Can someone please tell me how to solve this problem. Or at least set me up with the equations.


Thanks.

Read that, it should help you out.

wow man that's an awesome resource. i love anything that uses plain english.

have any links to the same person talking about power/force/energy/friction?

seeing as i tried that equation and apparently i still have the wrong answer...anyway i can get a step by step? i must be missing something?
 

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...
