Question

Two persons A &B are located at points (0,0) & (o,10) respectively. At a time t =0 they strat simultaneously with velocity Va=2j m /sec & 2i m/sec respectively. The time after which A &B are at closest distance is...

Answer 1

*

Answer 2

any information given about the direction of velocity?

Answer 3

^ j and i are given.

Answer 4

That's right ..A (0,0) is moving along Y axis and B (0,10) is moving parallel to x-axis. Both are with the same speed of 2 m/sec.We now need to calculate the time t when persons A &B will be closest..
