Two particles a and b are initially at distance d apart. they start moving simultaneously at velocity v and u such that a always move towards b and b moves along fixed straight line which is perpendicular to initial direction of motion of a. then particles will meet after time a. (vd)/(v^2-u^2)b. (ud)/(u^2-v^2)c. d/(v^2+u^2)^1/2 d. vd/(v^2+u^2)

Let after time "t" the Position of A and B are in such a way that A is heading to B and its velocity makes some angle with x axis

So the relative speed of A with respect to B in horizontal direction is given as

relative motion in y direction is given as

from first equation we can say

now in the direction of approach of each other

this is a good question! i'll do some research and come back when i have the answer!

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
