A block BB is pushed momentarily along a horizontal surface with an initial velocity vv. If μ\mu is the coefficient of sliding friction between BB and the surface, block BB will come to rest after a time A block B is pushed momentarily along a horizontal surface with an initial velocity v . If μ is the coefficient of

Options

  1. Avgμ\frac{v}{g \mu}
  2. Bgμv\frac{g \mu}{v}
  3. Cgv\frac{g}{v}
  4. Dvg\frac{v}{g}

Correct answer

A. vgμ\frac{v}{g \mu}

Step-by-step solution

Block BB will come to rest, if force applied to it will vanish due to frictional force acting between block BB and surface, iei e, force applied = frictional force ie, μmg=ma\quad \mu m g=m a or μmg=m(vt)t=vμg\begin{aligned} \mu m g & =m\left(\frac{v}{t}\right) \\ t & =\frac{v}{\mu g} \end{aligned}
