Suddenly it is struck horizontally by a 5.00 kg steel dart that embeds itself in the lead sphere. What must be the minimum initial speed of the dart so that the combination makes a complete circular loop after the collision?Two wooden pucks approach each other on an ice rink as shown in the figure. Puck #2 has an initial speed of 4.08 m/s and a mass that is some fraction f =2 that of puck #1. Puck #1 is made of a hard wood and puck #2 is made of a very soft wood. As a result, when they collide, puck #1 makes a dent in puck #2 and 14.8% of the initial kinetic energy of the two pucks is lost. Before the collision, the two pucks approach each other in such a manner their momentums are of equal magnitude and opposite directions. Determine the speed of the two pucks after the collision. m/s m/s Puck #1 40° 40° Puck #2

- 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.
