Question
Transcribed Image Text: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 Cafter 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.
Find the magnitude of the velocity of the center of mass before the first collision.
