A block slides down a rough inclined plane of slope angle θ 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

a
v24gsinθ
b
v22gsinθ
c
v2gsinθ
d
4gv2sinθ

detailed solution

Correct option is A

ad=gsin⁡θ−μkcos⁡θau=gsin⁡θ+μkcos⁡θ,v2−u2=2as
