Compare the collision between two baseballs and a catcher's mitt. Case A: A baseball pitched at 40 m/s collides with a catcher's mitt and is brought to a stop. The catcher holds the mitt rather rigidly and retracts backwards very little as the ball strikes the mitt. Case B: An identical baseball pitched at 40 m/s collides with a catcher's mitt and is brought to a stop. The catcher holds the mitt with a relaxed arm and reracts backwards 30 cm as the ball strikes the mitt.
Which variable is different for these two cases?
Which case involves the greatest momentum change? … the greatest impulse? … the greatest force?
