A block of mass 5.00 kg rests on a horizontal surface where the coefficient of kinetic friction between the two is 0.200. A string attached to the block is pulled horizontally, resulting in a 2.00 m/s² acceleration by the block. Find the tension in the string. Give your answer to 1 decimal place and include the appropriate unit.
