Two football players collide head-on in midair, moving along the same horizontal direction, while trying to catch a thrown football. The first player is 91 kg and has an initial velocity of 6.1 m/s (in the positive direction), while the second player is 115.5 kg and has an initial velocity of –3.65 m/s. What is their velocity in the horizontal direction just after impact if they cling together, in meters per second? vf =

5. Two balls, A and B, each of mass 1.0 kg, initially travel at the velocities VA = (10î + 20ĵ ) m/s and Vg = (-10î + 5j ) m/s, respectively. Immediately after their collision V = (-3î + 15j ) m/s. No net external force acts on the two balls. %3D What is the final velocity of ball A? What is the change in the balls' total kinetic energy?

Suppose M1 (1 kg) is moving at 3 m/s in the + x direction. M2 (2 kg) is moving at 3 m/s in the -x direction. If they collide and stick together, what will be their final velocity (in m/s)?
Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1400 kg and was approaching at 5.00 m/s due south. The second car has a mass of 850 kg and was approaching at 16.0 m/s due west. a. Calculate the final velocity (magnitude in m/s and direction in degrees counterclockwise from the west) of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the x-axis and y-axis; instead, you must look for other simplifying aspects.) magnitude m/sdirection ° counterclockwise from west b. How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars.) J

As part of a carnival game, a Mb=0.478 kg ball is thrown at a stack of 17.3 cm tall, ?o=0.343 kg objects and hits with a perfectly horizontal velocity of ?b,i=11.8 m/s. Suppose that the ball strikes the topmost object. Immediately after the collision, the ball has a horizontal velocity of ?b,f=5.10 m/s in the same direction, the topmost object has an angular velocity of ωo=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=12.1 cm below the point where the ball hits, what is the moment of inertia ?oIo of the object about its center of mass?
