Nice circular motion

but how first part give sol. plz

nooooooo.....

what is the proof for the third part

so how a exact ans.

it was asked at that instant....

how u answer part-a imagine its motion for a while u will see it is irregular [7]

oh yes.................what a foolish question by me.................thanxx

in third q does v_B/A denote the relative velocity

relative velocity

sory for my first ans i have mistaked with other question please check my soln

angular velocity of the line=v_net/r
=12-3/2
=9/2

answer for 2;
------
should be w2-w1=4-3=1rad/s;

for q2
-----------
ummm........

please reply fast eureka i know dat i was rong

wat is the ans for the first part eureka

yes yes..............2nd part answer is 1r/s..its easy........plzz try 1st parrt.........

hey eureka how part c & a is some wat typical if motion is analysed so its angular vel. is not const. in mag. & direction too

answer of part b is 1 rad/s

* shows vector product

2)ang vel of B wrt to A =3i*12j/(3)²-i*3j/1²=v_B/A

This will helps u for the third ques also
