Physics Problem - Elastic Potential Energy - Springs - Speed and Distance

A 0.500 kg block, attached to a spring with length 0.60 m and force constant 40.0 N/m, is at rest with the back of the block at point A on a frictionless, horizontal air table. The mass of the spring is negligible. You move the block to the right along the surface by pulling with a constant 20.0 N horizontal force.
(a) What is the block’s speed when the back of the block reaches point B, which is 0.25 m to the right of point A?
(b) When the back of the block reaches point B, you let go of the block. In the subsequent motion, how close does the block get to the wall where the left end of the spring is attached?

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.
