A baseball approaching a batter with a speed of 25 m/s is hit and leaves the bat in the directly opposite direction with a speed of 50 m/s. The mass of the baseball is 0.15 kg.

a) What is the magnitude of the impulse (in N · s) exerted by the bat on the baseball?

b) If the time of contact between the bat and the baseball is 2.9 ms, what is the average force exerted by the bat on the baseball during this time interval? (Enter the magnitude in newtons.)
