0.50\,\text{kg}

ball is rolling on a horizontal floor with a speed of

10\,\text{m\,s}^{-1}

. Due to the opposing force of friction, the ball comes to rest after travelling

20\,\text{m}

. (i) Calculate the work done by the frictional force on the ball. (ii) Hence determine the magnitude of the frictional force acting on the ball.
