A block of mass 10 kg is moved 20 m to the right over flat ground. If the coefficient of kinetic friction between the block and the ground is 0.4, then how much work does the kinetic frictional force do in moving the block? Write your answer down in units of Joules, but only write down the number part of your answer. 784 Ⓒ-784 922 -922
