The 10-kg crate is subjected to a force having a constant direction and a magnitude F = 100 N. When s = 15 m, the crate is moving to the right with a speed of 8 m/s. Determine 1) The normal force between the crate and the ground. 2) Its speed when s = 25 m. %3D The coefficient of kinetic friction between the crate and the ground is mk = 0.25.
