Given that the mass of the body is \\\\(0.25 kg\\\\) is at rest initially. when the body is hit by the stick it gains speed of \\\\(10\\ m/s\\\\).means initial speed \\\\(u = 0\\\\) and after getting hit it's final speed \\\\( v = 10 m/s\\\\).we know that impulse is equal to change in momentum i.e. \\\\(\ ext {Impulse } J =m(v-u)\\\\)so here \\\\( J = 0.25 ( 10 - 0 )\\\\) \\\\(kg\\ m/s\\\\) or \\\\( N \\\\)hence The impulse imparted to the ball is \\\\(2.5 N s\\\\)
