A particle moves on a rough horizontal ground with some initial velocity \(v_{0}\). If \(\frac{3}{4}\)th of its K.E. is lost in friction in time t0, the coefficient of friction between the particle and the ground is
- \(\frac{v_{0}}{2 g t_{0}}\)
- \(\frac{v_{0}}{4 g t_{0}}\)
- \(\frac{3 v_{0}}{4 g t_{0}}\)
- \(\frac{v_{0}}{g t_{0}}\)
Answer
(A) v_ 0 2 g t_ 0
