8. An object (A) of mass mA = 30.5 kg is moving in a direction that makes angle of 60° south of west with a speed VA= 5.00 m/s, while object (B) of mass mg = 16.0 kg is moving due north with a speed VB = 8.05 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision. m/s

As part of a carnival game, a mb=0.603 kgmb=0.603 kg ball is thrown at a stack of 16.8 cm16.8 cm tall, mo=0.343 kgmo=0.343 kg objects and hits with a perfectly horizontal velocity of vb,i=11.6 m/s.vb,i=11.6 m/s. Suppose that the ball strikes the topmost object. Immediately after the collision, the ball has a horizontal velocity of vb,f=3.60 m/svb,f=3.60 m/s in the same direction, the topmost object has an angular velocity of ωo=2.03 rad/sωo=2.03 rad/s about its center of mass, and all the remaining objects are undisturbed. Assume that the ball is not rotating and that the effect of the torque due to gravity during the collision is negligible. If the object's center of mass is located r=11.8 cmr=11.8 cm below the point where the ball hits, what is the moment of inertia IoIo of the object about its center of mass?   What is the center of mass velocity vo,cmvo,cm of the tall object immediately after it is struck?

Two gliders with mA = 0.50 kg, mB = 0.40 kg, collide elastically on a frictionless surface. Glider A with a spring bumper initially moves to the right with the speed of 4.0 m/s and glider B with a spring bumper initially moves to the left with the speed of 7.0 m/s. What is the final velocity of the glider A after collision?

Jack (mass 56.0 kg) is sliding due east with speed 8.00 m/s on the surface of a frozen pond. He collides with Jill (mass 49.0 kg), who is initially at rest. After the collision, Jack is traveling at 5.00 m/s in a direction 34.0 degrees north of east. Ignore friction. What is the magnitude of the Jill's velocity, after the collision, as she travels at an angle of 35.95 degrees south of east?
