Answer to Question #320088 in Classical Mechanics for Fs.Alberto

Question #320088

 Assume that yo-yo drops 1.0 m vertically from its owner's hand at a uniform speed of 0.80 m/s along its string. At the end of the string, it changes direction in 0.10 s and rises toward the owner's hand at a uniform speed of 0.60 m/s. Compute the average acceleration of the yo-yo at the bottom end of the string as it changes direction.

Answer

acceleration is that

a=vvtt=0.8+0.60.1=14m/s2a=\frac{v-v'}{t-t'}\\=\frac{0.8+0.6}{0.1}\\=14m/s^2
