4. A spiral staircase in a building is in the shape of a helix of radius 5 meters. Between two floors of the building, the stairs make one full revolution and climb by 4 meters. A person carries a bag of groceries up two floors. The combined mass of the person and groceries is 70 kg and the gravitational force is 70g downward, where g is the acceleration due to gravity. Calculate the work done by the person against gravity.
If blocks A and B of mass 10 kg and 6 kg, respectively, are placed on the incline and released, determine the acceleration and the tension in the link. The coefficients of kinetic friction between the blocks and the inclined plane are μA = 0.1 y HB = 0.3. Ignore the mass of the link. 6
