Unformatted text preview: t = 1.0 s, Eq. 710 gives K = K i + W = 0.64 J 0.6 J ≈ , where the second significant figure is not to be taken too seriously. (b) At t = 5.0 s, the above method gives K = 0. (c) Evaluating the W = 2 50 t ( t – 10) expression at t = 5.0 s and t = 1.0 s, and subtracting, yields –0.6 J. This can also be inferred from the answers for parts (a) and (b)....
