Problem
A 1.0kg block is pushed at constant speed across a rough table from point X to point Y, a straight-line distance of 0.80m, against a kinetic‐friction force of 2.0N. An identical block is moved from X to Y along a zig-zag route that is 1.2m long on the same table, experiencing the same friction force magnitude. Which block has the greater total work done on it by kinetic friction? Explain your reasoning briefly.
