Two boys are standing at the two end-points A and B of a field where AB = a. The boy at B now starts running at a uniform speed `v_(1)` in a direction perpendicular to AB. Simultaneously, the boy at A also starts at a uniform speed v along a straight line and meets B after a time t. Find t.

Text Solution

Verified by Experts

The correct Answer is:
`sqrt(a^(2)//(v^(2)-v_(1)^(2)))`
