is moving in right direction with a uniform velocity v and end of rod which is in contact with ground is moving in left direction with a velocity v Find the rate at which the angle is changing in terms of v v R and 0 Solution R Figure 1 52 x R cosece Differentiating with respect to time we get dx dt 11 Here x is the separation between centre of hemisphere and the end of rod Rate of change of x can be taken as the relative velocity of end of rod and hemisphere centre i e v v We are required to find the rate of change of 0 and rate of change of x we know so we have to develop a relation between x and 0 which is given as V2 R cosece cote iii An morning sun in h an angle the spe ground v cosa de dt iv Fi m han end of horizo speed the m string horiz u co v heig spee 4 0 vi
