1.

A body is projected up along an inclined plane from the bottom with speed V_(1).If it reachesthe bottom of the plane with a velocity V_(2),find (v_(1)//v_(2)) if thetais the angle of inclination with the horizontal and mu be the coefficient of.

Answer»

`(SIN theta + MU COS theta)/(sin theta - mu cos theta)`
`sqrt((SIIN theta + mu cos theta)/(sin theta - mu cos theta))`
`(cos theta + mu sin theta)/(cos theta - mu sin theta)`
`sqrt((cos theta + musin theta)/(cos theta - musin theta))`
