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.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
