WebNov 19, 2015 · The friction work is given by: W f = F f x, or: W f = μ m g x. Where x is the displacement over the time t. We know from above that the acceleration a is: a = F m − μ g, and the displacement x is: x = a t 2 2 = 1 2 ( F m − μ g) t 2 = 1 2 v t. So for W f we get: W f = 1 2 μ m g v t. The total work W B now done becomes: W B = m v 2 2 + μ m g v t 2.
