The figure shows the view looking down onto an air hockey table. A puck collides with a stationary bar. The collision is completely inelastic.The bar has mass M = 1.44 kilograms and length L = 1.14 meters. The puck has mass m = 0.488 kilograms and is initially moving at vi = 6.83 perpendicular to the bar. The puck collides with the bar at a location of b = 0.505 meters from the center of the bar. Note that the size of the puck is negligible compared to the length of the bar. vf = 1.729. Calculate the angular speed (rad/s) about the center of mass of the puck-and-bar system just after the collision.
In the figure, block 1 of mass m, slides from rest along a frictionless ramp from height h = 2.5 m and then collides with stationary block 2, which has mass m2 = 4m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction Hy is 0.15 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic?

Two spheres collide on a horizontal surface (all velocities, before and after the collision, are in the x-y plane). Throughout this problem, assume that all forces aside from those exerted by the spheres themselves are negligible (at least in comparison). Sphere A has a mass of 0.65 grams. It has an initial speed of 6.0 m/s and an initial velocity that is oriented at an angle of θ A i = 28 degrees below the x-axis. Sphere B has a mass of 0.45 grams. It has an initial speed of 6.5 m/s and an initial velocity that is oriented at an angle of θ B i = 35 degrees above the x-axis. After the collision, sphere A has a speed of 3.5 m/s and a velocity that is directed at an angle of θ A f = 16 degrees above the x-axis. What is the final speed, in units of meters per second, of sphere B?
A car with mass mc = 1216 kg is traveling west through an intersection at a magnitude of velocity of vc = 5.5 m/s when a truck of mass mt = 1819 kg traveling south at vt = 7.8 m/s fails to yield and collides with the car. The vehicles become stuck together and slide on the asphalt, which has a coefficient of friction of μk = 0.5. How far, in meters, will the vehicles slide after the collision?
A person is crossing a bridge. The bridge is 3.2 meters long and is 25 kg. One side of the bridge rests on the ground while the other side of the bridge is elevated 25 degrees above the ground. The end of the bridge that is elevated is connected to a rope, which is attached to a overhanging section of a cliff. The person walking across is 62 kg, and walks three quarters of the way to the rope end of the bridge then stops. Please determine the magnitude of the force that the ground exerts on the bridge.
