Work and Energy


<div class="wp-block-create-block-problemblock">A solid brass block of mass m slides along a frictionless track when released from rest along the straight section.  The circular loop has a radius R.<br /><img src="/old/images/work-and-energy.gif"  alt="work and energy physics problem ><br />A. What is h in terms of R if the block is on the verge of leaving the track when it reaches the top of the loop? <br">B. Assume the block is released at height h = 6.0 R, what are the magnitude and direction of the horizontal force competent acting on the block at point Q?</div>
