Jeanne rolls a 7.0 kg bowling ball down the alley for the league championship. One pin is still standing, and Jeanne hits it head-on with a velocity of 9.0 m/s. The 2.0 kg pin acquires a forward velocity of 14 m/s. What is the new velocity of the bowling ball?

Answer #1

This can be solved using the conservation of momentum,

Substituting the values in the equation we get,

therefore 5 m/s is the new velocity of the bowling ball
