Find out the normal force for a laundry basket with a mass of 3.4 kg in each of the following situations

(a) at rest on a horizontal surface

(b) at rest on a ramp inclined at 12° above horizontal

(c) at rest on a ramp inclined at 25° above horizontal

(d) at rest on a ramp inclined at 45° above horizontal

Question2

Some sliding rocks advance base of a hill with a speed of 16.0 m/s. The hill rises at 44.0 degrees above horizontal and has coefficients of kinetic and static friction of 0.420 and 0.580, respectively, with these rocks. Start each part of the solution to this problem with a free-body diagram.
