A body of mass executes SHM on a rough horizontal plane (friction coefficient ). Plot the restoring (friction) force as a function of time. The kinetic friction force on the block, as a function of time over the oscillation, is:
Options:
Answer:
B
Solution:
Kinetic friction has constant magnitude and always opposes the velocity. The velocity reverses at each extreme, so the friction force flips sign every half oscillation, giving a square wave.
