1.	A block slides down a rough inclined plane of slope angle theta with a constant velocity. It is then projected up the same plane with an initial velocity v. The distance travelled by the block up the plane before coming to rest is
Answer» `(v^(2))/(4G sin theta)` `(v^(2))/(2g sin theta)` `(v^(2))/(g sin theta)` `(4gv^(2))/(sin theta)` Solution :`a_(d)=g(sin theta-mu_(k)COSTHETA)` `a_(u)=g(sin theta+mu_(k)cos theta), v^(2)-u^(2)=2AS`
