Question

A player bounces a 0.43-kg
soccer ball off her head,
changing the velocity of the
ball from u = 8.8 i - 2.3 j to v
= 5.2 i + 3.7 j. If the ball is in
contact with the player's
head for 6.7
6.7 ms,
the
magnitude of the impulsein
kg.m/s) delivered to the
ball?(All components of
velocities in vectors u and v
are in m/s)​

Answer 1

Answer:

its just confusing bcoz of velocity vectors
