Find the speed of two objects if, when they move unifromly towards each other, they get 4.0 metre closer each sec and when they move uniformly in the same direction with the original speeds, they get `4.0 m` closer each 10 s.

Text Solution

Verified by Experts

The correct Answer is:
2.2 m/s and 1.8 m/s

`v_(1) + v_(2) = 4`
`v_(1) - v_(2) = 0.4`
Where `v_(1)` and `v_(2)` are the speeds of the moving objects
