A baseball player pitches a fastball toward home plate at a speed of 41.0 m/s. The batter swings, connects with the ball of mass 335 g, and hits it so that the ball leaves the bat with a speed of 37.0 m/s. Assume that the ball is moving horizontally just before and just after the collision with the bat. (a) What is the impulse delivered to the ball by the bat? Enter a positive value if the impulse is in the direction the bat pushes the ball and enter a negative value if the impulse is in the opposite direction the bat pushes the ball. ____kg·m/s (b) If the bat and ball are in contact for 3.00 ms, what is the magnitude of the average force exerted on the ball by the bat? ____kN

A careless driver driving at 25 m/s hit a tree while fumbling with his phone. Assume the driver was in contact with the air bag for 0.22 seconds, and his upper body has 37 kg in mass, then how much average force (absolute value) does the air bag exert on the driver's upper body? Ignore gravity since the force was horizontal. Hint: use impulse and the change of momentum.
