Question

Mike shoots a large marble (Marble A, mass: 0.05 kg) at a smaller marble (Marble B, mass: 0.03 kg) that is sitting still. Marble A was initially moving at a velocity of 0.6 m/s, but after the collision it has a velocity of –0.2 m/s. What is the resulting velocity of marble B after the collision? Be sure to show your work for solving this problem along with the final answer.

Answer 1

Use
m1*u1+m2*u2=m1*v1+m2*v2

Answer 2

Given
m1=0.05kg
m2=0.03kg

Answer 3

u1=0.6m/s
u2=0

Answer 4

v1=-0.2m/s
v2=?
