Question

Question 3 A spring of spring constant k is compressed by a distance d by a mass mi and released. This propels the mass down a flat track. Another spring, also of spring constant k, is on the other side. Another object of mass m is sitting in the middle of the track. The first mass strikes it and sticks to it. he entire track is frictionless, except for a small region of the track to the left of m2, of width b, with a coefficient of kinetic friction μ. (This is indicated by diagonal lines on the track in the diagram) m2 a) How fast is the first mass moving right before it collides with the second block? (5 points) b) How fast are the two masses moving right after the collision? (5 points) c) When the two blocks reach the spring on the other side, they will bounce off of it, compressing it in the process. What is the maximum distance that this spring is compressed? (15 points) Suppose that the numeric quantities in this problem are as follows: ·k = 1000 N/m d) How many times will the blocks cross the track before they come to rest? (10 points extra credit) Hint There is an easy way and a hard way to do this!

Answer 1

2. 2 V. 3
