3kg ball traveling at 10 m/s east collides with 5 kg ball traveling at 2m/s east after the collision the balls stick together what is the final velocity of the 3kg ball ?

Explanation:

The formula for this is designed around the fact that momentum must be conserved:

This is because they sitck together after they collide. Filling in:

[(3*10)+(5*2)] = [3 + 5]v and

30 + 10 = 8v so

40 = 8v and

v = 5

They are both moving east at a velocity of 5 m/s since they stuck together.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
