SUMMARY

The discussion focuses on solving a physics problem involving a ball rolling down a ramp and determining the time it takes to reach a specific position. The method discussed involves calculating the time t when the x position equals the width of the ramp and subsequently evaluating the vertical position y(t) to compare it with the ramp's height. Participants noted that the initial approach lacked a crucial component in the equation for y(t), which is essential for accurate evaluation. This highlights the importance of ensuring all variables are accounted for in kinematic equations.

This is from a practice exam without an answer key. I tried the problem once before and am getting a different solution now. My method is solving for the time t when the x position is the width of ramp, and then evaluating y(t) to see if it is more or less than the height of the ramp.

The problem statement, relevant equations, and attempt are in the image.

That sounds like a reasonable method - what did you do before?

There is something missing from your equation for y(t)
