Tasha rolls a 7.0 bowling ball down 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 2.0pin acquires a forward velocity of 14.0m/s. what is the new velocity of the bowling ball

Explanation:

Let be the velocity of the bowling ball before collision.

Let be the velocity of the pin before collision.

Let be the velocity of the bowling ball after collision.

Let be the velocity of the pin after collision.

Let be the mass of the bowling ball.

Let be the mass of the pin.

According to the conservation of momentum,

Given,

New velocity of bowling ball is

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
