Answer 1

10.

an object of mass 600 g moving initially along the positive x-direction at velocity 4 m/s undergoes a blast and breaks into two smaller object of mass 400 g and 200 g such that 400 g portion moves in the same direction at velocity of 3 m/s . determine the velocity of other smaller portion

let the velocity of other portion be v_2x

using conservation of momentum

600 (4) = (400) (3) + (200) v_2x

v_2x = 6 m/s
