An impulse of 21 N*s is exerted on a 0.3 kg baseball traveling 72 m/s west. What is the velocity of the baseball after it has been hit? Report your answer to 1 decimal place.

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.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
