Problem

A 2 kg2\,\text{kg} block initially at rest is pushed along a smooth horizontal surface. After the block has moved 10 J10\,\text{J} of net work has been done on it. Calculate the final speed of the block. a) 4.5 m s−14.5\,\text{m\,s}^{-1} b) 2.2 m s−12.2\,\text{m\,s}^{-1} c) 3.2 m s−13.2\,\text{m\,s}^{-1} d) 5.0 m s−15.0\,\text{m\,s}^{-1}
