2 bodies of equal masses are kept stationary at same position.Impulse I and force F is applied to the first and second body respectively.Please help to prove t=2I/F if the 2 bodies again meet after time t.
Since objects at rest ,
An impulse is applied to it, then the impulse that gives a stationary object a momentum
`mv` , where v is the velocity gained .
Force F is applied to another object of mass m for t second,again this force will produce a velocity
Impulse =rate of change of momentum =m(v-0)/t=(mv)/t
After t second both meet
Impulse +t (mv)/t=F.t
