what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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.
