Question

A spring of spring constant k = 400 N/m is compressed .300 m by a 2.00 kg block. Both the spring and block are on a horizontal, frictionless surface and the block is held motionless until t = 0, when it is then released. Once the spring is finished pushing on the block the block slides down a frictionless slope with a total vertical change in elevation of 115 m. At the bottom of the slope the block encounters a horizontal surface, which for 3.00 m exerts a frictional force of 10.0 N on the block. The block then passes back onto a horizontal, frictionless surface, collides with a stationary 3.00 kg block and sticks to it. What is the final velocity of the blocks? (20 points) What kind of problem(s) is this? Hint: there are two problems here. What are they? Draw a diagram of the first problem. List your hidden information here, if any: What are the energy transformations? What is your basic equation? List it here. Highlight what you know by circling and what you want by inscribing in a square. Use the puzzle method questions (list them as you go) to solve this first problem. For the second problem: List your hidden information here, if any: Draw a diagram of the second problem: Write out your basic equation for this second problem and highlight what you know by circling and what you want by inscribing in a square. Use the puzzle method questions (list them as you go) to solve this second problem.
