Answer 2

EXPLANATION: :

We can find the impulse experienced by the ball from the definition of the impulse:

J=Δ p=m(vf−vi)

Or,J=0.20kg×{(–60m/s)–40m/s}

Or,J= —20kgm/s.

The sign minus means that the impulse experienced by the ball directed toward the pitcher.

Answer:

J=20\ \dfrac{kgm}{s},J=20 skgm, toward the pitcher.

ANSWER: :

J=20kgm/s towards the pitcher.
