Answer:
A) The direction of impulse is the opposite direction to the velocity direction of travel of the baseball.
B) Magnitude of Impulse = 0.6175 N.s
Explanation:
A) From the question we see that there is no change in direction and thus the impulse will be in exactly the opposite direction to the velocity direction of travel of the baseball.
B) From momentum and impulse we know that;
Impulse = change in momentum
Thus, impulse = (V2-V1)m
So;
(10.1 - 14.3)m/s x 0.147 kg = -0.6175N.s
(The negative sign indicates an opposite direction to that of the velocity)
Thus, the magnitude of the impulse is 0.6175 N.s
