Help Save &Exit Submit Check my work Three small identical spheres A-8, and C, which can slide on a horizontal, frictionless surface, are attached to three strings, 0.25 ft long, which are tied to a ring G. Initially the spheres rotate counterclockwise about the ring with a relative velocity of 2.5 ft/s and the ring moves along the x axis with a velocity vo (1.25 f/s)i. Suddenly the ring breaks and the three spheres move freely in the xy plane...

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...

Two objects slide towards each other across a frictionless surface. Object 1 with a mass of 3.50 kg initially slides to the east with a speed of 0.750 m/s. Object 2 slides in the direction 30.0◦south of west with a speed of 1.25 m/ s. After colliding, the two objects stick together and slide due south. What is the final speed of both objects after the collision?

The figure in the next slide shows two battling robots on a frictionless surface. A robot A with mass 20 kg, initially moves at 2.0 m/s parallel to the x-axis. It collides with robot B, which has mass 12 kg and is initially at rest. After the collision, robot A moves at 1.0 m/s in a direction that makes an angle alpha = 30 degree with its initial direction. What is the final velocity of robot B?
