Problem

2.0\,\text{kg}

block is released from rest on a frictionless

30^{\circ}

incline. What is the magnitude of its acceleration down the plane? (Take

g = 9.8\,\text{m}\,\text{s}^{-2}

.) a)

9.8\,\text{m}\,\text{s}^{-2}

5.7\,\text{m}\,\text{s}^{-2}

4.9\,\text{m}\,\text{s}^{-2}

8.5\,\text{m}\,\text{s}^{-2}
