140gm baseball travel 39m/s hits bat and travels at 45m/s at 30degree angle above horizontal,ball in contact wiht bat for 1.2ms calculate magnitude of average force on ball by bat
Calculate the magnitude of the momentum change, treating the incoming ball as horizontal (e.g., a fast ball, not a sinker). You may have to use the law of cosines. They should have told you what direction to assume for the pitched ball.
Divide the momentum change magnitude by the time of contact to get the average force.
