39dude, u need to ineterchange positions of r and R in your answer
a spool consists of a cylindrical core and 2 identical heads. the core rolls without slipping along a rough horizontal block with a constant velocity `v`. the radius of the core is `r` and that of the heads is `R`.
what instantaneous velocity will points A and B on the rim of one of the heads have? what points on the heads have an instantaneous velocity equal in magnitude to the velocity of the spool core.

9A - v[1 + R/r]
B - v[1 - R/r]
for part 2 of ques locus is
(x+r)2+y2 = r2 with origin as centre of head
