A softball of mass .4kg is pitched at a speed of 24 m/sec, the batter hits it back directly at the pitcher at a speed of 20 m/s. The bat acts on the ball for .015 secs. A: What is the impulse imparted on the ball? B: What is the average force exerted by the bat on the ball?
pi= mv pi= (.4)(25)= 10
pf=mv pf= (.4)(20)= 8
F=Δp/t =10-(-8 )/ .015 = 1200 N
I= Δp = 18 NS
Is this right?
