The 35-kg crate is subjected to a force inclined to 700 respect to vertical plane having a constant direction and a magnitude F = 150 N. When s = 20 m, the crate is moving to the right with a speed of 10 m/s. Calculate for normal reaction and its speed when s = 30 m. The coefficient of kinetic friction between the crate and the ground is mk = 0.35.
