Momentum & Energy: Masses of A & B, Collision, Maximum Compression

AI Thread Summary
During the collision between blocks A and B, the maximum compression of the spring occurs when both blocks share the same velocity. This is due to the conservation of momentum, as the total momentum before the collision must equal the total momentum after. As block A strikes the spring, it compresses while transferring energy to block B, which remains stationary initially. The spring's compression indicates that block A is slowing down while block B begins to move. Understanding this relationship clarifies the dynamics of the collision and the behavior of the spring.

Homework Statement


The masses of blocks A and B are 2 kg and 3 kg, respectively. Block A slides to the right on the smooth surface and strikes the spring attached to stationary block B. The spring deforms during the collision process. What quantity do the blocks have in common at the instant the spring has the maximum compression?

The answer is velocity and I'm unsure how.

Homework Equations


mv1 + ∫ΣFdt = mv2

If the velocities are not the same, what is happening to the length of the spring?

You slick guy you... compressing or extending. Makes sense now. Thanks.
 

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 .
