So, it's asking the minimum distance B and C can be so that B does not hit C when A hits B?

One of three blocks is attached to ceiling by a cord. Two others are connected by springs to the first block and to each other with coefficient k. What's the deformation of the springs? What's the tension in the cord? If the cord is cut, what's the acceleration of the blocks? I'm somewhat...

Tell me if this question makes any sense. One block moving with velocity v_0 hits a system of two blocks at rest connected by an undeformed spring with spring constant k. Find the minimum distance between the blocks attached to the spring. All masses are of equal mass. I'm not quite sure...

I have another problem. These are both bonus problems for my physics class. One block of mass m is stacked on another block of mass M. Coefficient of friction between table and block is u and between blocks is u. There is a force acting on the lower block. What is the minimum magnitude of...

I would appreciate any help, even a nudge in the right direction. Problem: A rectangular block of mass m was put on a triangular block of mass M. (There's a diagram for this, but imagine a right triangle, with a square on the hypotenuse, as it slides down.) Assume all friction forces can be...

I asked him about both questions. For #3, I asked him if it's possible for the train to be of length 7m and the back of the train arrives at a distance of 8m. He responded by saying he didn't understand the question and to assume the train is a particle, an object. So, I responded that it's...

Im pretty sure i didnt miss the first problem because of units. I was just on the phone with him, and he said plug in the acceleration and see what final velocity you get. Plugging in a=-4.89 the final velocity isn't 0. That made me think, why not just use a=(vf-vi)/t to get a=-10/3. Of course...

This was my professor of mine who graded it. To answer your question, no the number of pillars is not equal to the number of pillar spacings. The number of pillar spacings is one less, 31. Therefore, he should've calculated the velocity as 31km/h. I did this in my solution, and said the velocity...

These are bonus problems for a Physics 1710 class. Homework Statement A train is decelerating with initial velocity 10 m/s. What should be the acceleration of the train for stopping in 3 seconds at distance of 8m. Homework Equations The Attempt at a Solution L=vt + at^2 /2...
