AI Thread Summary
The discussion revolves around a collision problem involving two masses where mass 1 is moving and mass 2 is at rest. The user calculated the final velocities of both masses after the collision, arriving at 0.0838 m/s for mass 1 and 2.08 m/s for mass 2. They confirmed using both momentum and energy conservation principles in their calculations. Other participants validated the approach, emphasizing the importance of using both methods for accurate results. The conversation highlights the integration of momentum and energy in solving collision problems.

Homework Statement



A mass 1 is moving at a constant velocity and collides with a ball of mass 2 that is at rest. What are the final velocities of the masses and the direction of the velocity?

Mass 1 = 4.35kg
Initial Velocity of mass 1= 2m/s
Mass 2 = 4.00
Initial Velocity of mass 2 = 0 m/s

The Attempt at a Solution



I calculated .0838 m/s for the mass 1 and 2.08 m/s for mass 2. I used momentum to calculate the answers. Can anyone check this?

That's right. But you didn't just use momentum, did you? You used energy as well.
 
yes I used both together. Thanks
 

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...
