A block of mass m = 1.0 kg is placed at rest at a distance 8.15 m (measured along the slope) from the horizontal plane on an incline whose surface makes θ=25o to the horizontal as shown in Figure 2. The coefficient of kinetic friction between the surface where the block is placed and the block is μk = 0.19. After the block starts descending on the slope, find the block’s speed at the time when it reaches the bottom of the incline in m/s2. 0
