Part A The block shown in (Figure 1) has mass m = 7.5 kg and lies on a fixed smooth frictionless plane tilted at an angle ( = 25.0" to the horizontal. Determine the acceleration of the block as it slides down the plane. Express your answer in meters per second squared. UAL AEd m/s? Submit Request Answer Part B If the block starts from rest AI = 14.0 In up the plane from its base, what will be the block's speed when it reaches the bottom of the incline? Figure
