AI Thread Summary
When an object is dropped from different heights, it will have the same speed at the same time if we assume no friction. The acceleration due to gravity is constant at -9.81 m/s² for both objects. Since both start from rest, their initial velocity is 0 m/s. Therefore, at any given time, they will reach the same velocity despite being dropped from different heights. This conclusion holds true only in the absence of friction.

When an object is being dropped at different height assuming no friction will it have the same
speed at the same time?

Lets say an object was dropped at 10m and 5m

at 3seconds would the speed be the same?

a=v/t
v=a*t

using the formula i would assume they would have the same velocity at the same time even in different heights.
is this correct?

i think you are correct because there is no friction so yes. if there was friction no.
 
Yes, because the initial velocity of both would be 0 m/s and gravity would at equally on them both at -9.81 m/s^2 so at the same time they would have the same speed.
 

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...
