The chart show the masses and velocities of two colliding objects that stick together after a collision. according to the law of conservation of momentum, the momentum of the object after the collision is answer 1,500 kg • m/s.

answer

1,500

kg • m/s.

answerscientific theory;

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
