Unformatted text preview: v < u reative to the ground. The velocity of the water before it hits the block is u relative to the ground, the cruss-sectional area of the water jet is A , and the density of water is ρ . The block has a kinetic friction coefficient μ k and the gravitational acceleration is g . a. Find the force that acts on the block from the water jet. b. Determine the steady state velocity of the block. c. if the static and kinetic friction coefficients are the same, what is the minimum jet speed for which the mass will move? d. What is the power of the action by the water jet on the mass M ?
