AI Thread Summary
To calculate the speed of a 145g baseball dropped from a height of 13.0m using the conservation of energy method, the initial potential energy (PE) is converted into kinetic energy (KE) just before impact. The initial energy is calculated as PE = mgh, where m is mass, g is gravitational acceleration, and h is height. The final energy is all kinetic, represented as KE = 0.5mv². By setting the initial potential energy equal to the final kinetic energy, the speed of the baseball at impact can be determined. This method effectively demonstrates the principle of energy conservation in physics.

Please help! Physics Qyestion!

1. A 145g baseball is dropped from a tree 13.0m above the ground. Using a conservation of energy method, find the speed of the ball just as it hits the ground. Ignore air resistance.



2. Sum Of Ei = Sum Of Ef. That is about as far as i got.



3. I don't know where to start!

Can you find expressions for the initial and final energies? What is each term the sum of?
 


Ok thanks i got it now!
 

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 .
