Question

how to find velocity of close approach give full explanation .​

Answer 1

Explanation:

Velocity of approach or separation is defined as the rate of change of relative displacement between two bodies (i.e. how fast a body approaches another body). Velocity of approach is defined when the displacement between the bodies is decreasing and separation when the displacement between the bodies is increasing.

Example:

When two bodies approach each other with different uniform speeds, the distance between them decreases by 120m per every 1min. Then, the velocity of approach is 120m/min=2m/s
