A body (mass m) is driven along a rough horizontal path (kinetic friction coefficient u) by a periodically acting force, such that v(t0) = v0 and v1 =v(t1) = v0/2. During the driving phase At, the force profile F(t) is triangular. a) Determine the period T and the required peak force T Fo to t1 FO for a given At. b) Calculate the work U done by F during a period T.
