A 1.8-kg block slides on a horizontal surface with a speed of v = 0.80 m/s and an acceleration of magnitude a = 2.8 m/s2, as shown in FIGURE 6-30. (a) What is the coefficient of kinetic friction between the block and the surface? (b) When the speed of the block slows to 0.40 m/s, is the magnitude of the acceleration greater than, less than, or equal to 2.8 m/s2? Explain.
