Показать описание
A `20 kg` block is originally at rest on a horizontal surface for which the coefficient of friction is `0.6`. A horizontal force `F` is applied such that it varies with time as shown in the figure (a) & (b). If the speed of the block after `10 s` is `8v` then find `v`. ( Take `g=10m//s^(2)`)
