At a waterpark, sleds with riders are sent along a slippery, horizontal surface by the release of a large compressed spring. The spring, with force constant k = 40.0 N/cm and negligible mass, rests on the frictionless horizontal surface. One end is in contact with a stationary wall. A sled and rider with total mass 70.0 kg are pushed against the other end, compressing the spring 0.375 m. The sled is then released with zero initial velocity. What is the sled’s speed when the spring
(a) returns to its uncompressed length
(b) is still compressed 0.200 m?

The best way to learn how to solve a Physics problem is to understand examples. NO AUDIO.
All problems are solved following the same basic problem-solving techniques: Break down the problem to identify given and unknown variables. Draw a model if needed. Identify relevant equations and concepts. Solve for the unknown variables. Evaluate equations with given variables.
Follow along as I break down the question and then use standard equations to solve the problem. FF, Pause, or Rewind as needed.
There are often multiple ways to get to the same answer, so don’t be concerned if your path is different, as long as the final answer is the same.
