The elastic collision between two bodies, A and B can be considered using the following model. A and B are free to move along a common line with out friction. When separation between the surfaces is greater then d= 1m,the interacting force is zero, when their distance less than d, a constant repulsive force F= 6N is present. The mass of body A ism_(A) = 1kg and it is initially at rest. The mass of body B is`m_(B)` = 3kg and it is approaching towards A with a speed`v_(0) = 2 m//s.` Then choose the correct option(s).

Options

A. the common velocity attained by the bodies are 1.5`m//s`
B. the minimum separation between the bodies is 0.25m
C. the minimum separation between the bodies is 0.75m
D. the common velocitya attained by the bodies are 2.0 `m//s`

Answer

A, C
