Physics Problem: Two Blocks Connected by String - Finding Mass

Explore a challenging physics problem involving two blocks connected by a string in this 13-minute video tutorial. Analyze a system where a block of unknown mass rests on a 5.00 kg block on a tabletop, connected by a light string passing over a frictionless peg. Given a coefficient of friction of 0.330 at both surfaces and a 67.0 N force pulling the blocks in opposite directions at constant speed, determine the mass of the upper block. Learn problem-solving techniques and apply fundamental physics principles to solve this complex scenario step-by-step.
