Sven hits a baseball

(m = 0.15 kg).

He applies an average force of 46.0 N. The ball had an initial velocity of 33.0 m/s to the right and a final velocity of 43.5 m/s to the left as viewed by a fan in the stands.

(a) What is the impulse delivered by Sven's bat to the baseball? (Assume to the right as viewed by the fan is positive. Indicate the direction with the sign of your answer.)
kg · m/s

(b) How long is his bat in contact with the ball?
s
