2. Lloyd rolls a 7.0 kg bowling ball down the alley for the league championship. One pin is still standing, and Lloyd hits it head-on with a velocity of 9.0 m/s. The 2.0 kg pin acquires a forward velocity of 14.0 m/s. What is the new velocity of the bowling ball? m=7.0kJ my + m,V2 = (m+m2)(Vf) %3D (7.0 V = 4.0mis V2=14.0mIS
