In order to complete a tough “split” in bowling, a bowling ball of mass 6.5 KG is rolled with a velocity of 12 M/S. The ball hits a 1.3 KG bowling pin, sending it off with the speed of 3.5 M/S at an angle of 80° with respect to the original direction of the bowling ball. What is the angle and direction of the bowling balls velocity after the collision with the pin?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
