A(n) 0.163 kg baseball is thrown with a speed
of 9.37 m/s. It is hit straight back at the
pitcher with a final speed of 16.7 m/s.
What is the magnitude of the impulse de-
livered to the ball?
Answer in units of kg · m/s.

p=mv

p(thrown)=(.163)x(9.37) =1.52731

p(hit back)=(.163)x(16.7)= 2.7221 (negative)

1.52731-(-2.7221)=4.24941 = impulse.

p.s. !@#$%^& you.
