The Hardest Exam I Ever Took at MIT in Physics

We used to solve these problems while preparing for IIT JEE (JEE Advanced). These problems are very common in I.E. Irodov, however sometimes you can end up disappointed if you depend too much on this, because there are only 2-3 problems that are even distantly related to classical mechanics in the entire exam. Also, I liked how you could solve the same problems by applying conservation of energy and force analysis. Conservation of momentum was also a handy tool. You need to know when exactly is the energy conserved and when momentum is conserved. The quicker you figure it out, the faster you solve the problem.
