Question

Cassy shoots a large marble (Marble A, mass: 0.06 kg) at a smaller marble (Marble B, mass: 0.03 kg) that is sitting still. Marble A was initially moving at a velocity of 0.7 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?

Answer 1

conservation of momentum

Answer 2

m1u1 +m2u2 = m1v1 + m2v2

Answer 3

m1 = 0.06; m2 = 0.03; u1 = 0.7; u2 = 0; v1= -0.2; v2 = ?

Answer 4

solve
