70 kg box is resting on a reclining floor. The coefficient of fricion between the floor and the box is: static = 0.30, kinetic = 0.10. If the floor is to be inclined at an angle of 10 deg., what is the needed minimum value of force T (applied to the object with a direction opposite to the direction of sliding) to prevent the box from sliding? Express your answer in unit of N. If the floor is to be inclined at an angle of 25 deg., what is the needed minimum value of force T (applied to the object with a direction opposite to the direction of sliding) to prevent the box from sliding? Express your answer in unit of
