Two blocks connected by a string are pulled across a horizontal surface

  • Two blocks in contact with each other are pushed to the right across a rough horizontal surface by the two forces shown. If the coefficient of kinetic friction between each of the blocks and the surface is 0.30, determine the magnitude of the force exerted on the 2.0-kg block by the 3.0-kg block. An object of unknown weight is suspended as shown.

    Example Problem: Two blocks are connected by a massless string around a frictionless pulley. Block A is sliding across a frictionless surface and is a = aA = aB. Since the string is massless, the tension is uniform throughout the system. The tension pulling Block A to the side is the same as the...

Find the magnitude of the horizontal force which will just turn the roller over the corner of the rectangular block.

    (Of course, if you're using C++, you'll read the characters into an std::string, and iterate over that, rather than having an almost guaranteed buffer overflow.) Note that I also exchanged your use of fixed-sized arrays with an std::string, so that you're not at risk of dangerous circumstances when someone...
