Two particles are initially located at points A and B distant d apart. They start moving at time t=0 such that the velocity `vecu` of B is always along the horizontal and velocity `vecv` of A is contiunously aimed at B. At `t=0 , vecu` is perpendicu lar to `vecv` The particles will meet after time:

A

`(vd)/(v^(2)-u^(2))`

B

`(v^(2)+u^(2))/(ud)`

C

`(v^(2)-u^(2))/(vd)`

D

`(ud)/((v^(2)-u^(2)))`

Text Solution
