A body slides down a smooth inclined plane of angle terha and takes time 't'. If the plane is rough with coifficient of fricton 'u' it takes time 'Pt'(P>1). Find u​

Answer 1

Explanation:

When a body slides down from rest along a smooth inclined plane making an angle of 45° with the horizontal, it takes time T. When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it is seen to take time pT, where p is some number greater than 1. Calculate the co-efficient of friction between the body and the rough plane.Read more on Sarthaks.com - https://www.sarthaks.com/109867/when-slides-from-rest-along-smooth-inclined-plane-making-angle-with-horizontal-takes-time

Answer 2

$u = \tan( \alpha (1 - 1 \div p {?}^{2} )$

Explanation:

Put P in place of n
