1no mass not reqd.
ab and cd smooth so their slope doesn.t matter jus use energy conservation
point a above b and b is the lower point of inclined plane
hotspot in the question is the part bc the inclined plane
ABCD is a track in the vertical plane AB and CD being smooth and concave upwards BC being an inclined plane with μs=0.3 , μk=0.2 and θ=tan-11/4. horizontal dist b/w B and C is 2 metres.
if the particle is released from rest at A find the horizontal distance between B and the point where it comes to rest.
vertical ht between B & A is 4.3 metres
A is above B and D is above A of course
dumb hint-
use energy conservation in path AB and CD

1no one yet so there are the options
a)0
b)1/3
c)2/3
d)3/2
in metres all of them
1are AB & CD both concave upward????
is mass not required?????
cant get the fig currently
