I Review | Constants
Sphere A, of mass 0.600 kg, is initially moving to the right at 4.00 m/s. Sphere B, of
mass 1.80 kg, is initially to the right of sphere A and moving to the right at 2.00 m/s. After
the two spheres collide, sphere B is moving at 3.00 m/s in the same direction as before.
(a) What is the velocity (magnitude and direction) of sphere A after this collision? (b) Is
this collision elastic or inelastic? (c) Sphere B then has an off-center collision with sphere
C, which has mass 1.60 kg and is initially at rest. After this collision, sphere B is moving
at 19.0° to its initial direction at 1.60 m/s. What is the velocity (magnitude and direction)
of sphere C after this collision? (d) What is the impulse (magnitude and direction) imparted
to sphere B by sphere C when they collide? (e) Is this second collision elastic or
inelastic? (f) What is the velocity (magnitude and direction) of the center of mass of the
system of three spheres (A, B, and C) after the second collision? No external forces act
on any of the spheres in this problem.
Part J
The second collision is two-dimensional, so you'll have to demand that both components of momentum are conserved. Use this to find the speed of sphere C after the second collision. (Hint: After the first collision,
sphere B maintains the same velocity until it hits sphere C.)
