1. The problem statement, all variables and given/known data A concrete block of mass 25kg is placed on a smooth slope that makes an angle of 30 degrees with the horizontal. Ignoring the effects of air resistance, calculate a) the acceleration of the block as it slides down (g = 9.81 ms-2) b) the distance the block moves in 3 seconds 2. Relevant equations 3. The attempt at a solution w = mg w = 25 * 9.81 = 245.25N Wsin(theta) = 245.25 * sin(30) = 122.625N 122.625N / 25kg = 4.905ms-2?
