The block slides at a constant speed on a surface with friction. In each case, the water jet has velocity 50 m/s and cross-sectional area 5 cm2, and the block has velocity 25 m/s. In case (a), the jet is deflected to an angle of 60° from horizontal relative to the block, as shown. In case (b), the jet is deflected 180°. Calculate the friction force in each case.
