two particles `A` and `B` are at separation of `100 m`. They move towards each other with uniform speed, `A` with `5 m//s` and `B` with `15 m//s`. When and where the two particle meet?

Two particles of masses 2 kg and 3 kg are at rest separated by 10 m. If they move towards each other under mutual force of attraction, the position of the point where they meet is

Two particles of masses 4 kg and 6 kg are at rest separated by 20 m. If they move towards each other under mutual force of attraction, the position of the point where they meet is

Two particles of masses 4 kg and 6 kg are at rest separated by 20 m. If they move towards each other under mutual force of attraction, the position of the point where they meet is

Two particles A and B are projected from ground towards each other with speeds 10 m//s and 5(sqrt2) m//s at the angle 30^@ and 45^@ with horizontal from two points separated by a distance of 15 m. will they collide or not ?

Two particles A and B are projected from ground towards each other with speeds 10 m//s and 5(sqrt2) m//s at the angle 30^@ and 45^@ with horizontal from two points separated by a distance of 15 m. will they collide or not ?

If in the previous problem, particle A moves with constant acceleration 4 m//s^(2) with initial speed 5 m//s and B moves with uniform speed 12 m//s , when and where the particle meet?

Two particles of masses 1kg and 2kg respectively are initially 10m aprt. At time t=0 , they start moving towards each other with uniform speeds 2m//s and 1m//s respectively. Find the displacement of their centre of mass at t=1s .
