A particle moves on a rough horizontal ground

Asked by admin @ 26/08/2021 in Physics viewed by 305 People

A particle moves on a rough horizontal ground with some initial velocity say V°. If

of its kinetic energyis lost due to friction in time t°, then coefficient of friction between the particle and the ground is :

Answered by admin @ 26/08/2021

Explanation:

If energy becomes 14 th .

34 th energy is lost, Velocity becomes v02 under retardation μg

v02=v0−μgt0

μ=v02gt0

Hence a is the correct answer
