A particle moves on a rough horizontal ground with some initial velocity say \( v_{0} \). If \( 3 / 4 \) of its kinetic energy is
\( \mathrm{P} \)
lost in friction in time \( t_{0} \) then coefficient of friction between the particle and the ground is
(1) \( \frac{v_{0}}{2 g t_{0}} \)
(2) \( \frac{v_{0}}{4 g t_{0}} \)
(3) \( \frac{3 v_{0}}{4 g t_{0}} \)
(4) \( \frac{v_{0}}{g t_{0}} \)
(4) (D) (D) (16) (a) (
