If a particle is projected vertically upward in a constant gravitational field with an initial speed v0. If there is a retarding force proportional to the square of the instantaneous speed, the speed of the particle when it returns to the intial position is v0vt/√(v02+vt2) where vt is the terminal speed.
A 2.1 kg block slides along a horizontal surface with a coefficient of kinetic friction μ k = 0.31. The block has a speed v = 1.4 m/s when it strikes a massless spring head-on.
