Statement of a problem № 11252


On earth a block has a weight of 88 N. This block is sliding on a horizontal surface on the moon, where the acceleration due to gravity is 1.60 m/s2. As the figure shows, the block is being pulled by a horizontal rope in which the tension is T = 24 N. The coefficient of kinetic friction between the block and the surface is μk = 0.20. Concepts: (i) Which of Newton s laws of motion provides the best way to determine the acceleration of the block? (ii) Does the net force in the x direction equal the tension T? Calculations: Determine the acceleration of the block. (a) (b) Free-body diagram for the block
