In the overhead view of Fig. 9-67, a \( 300 \mathrm{~g} \) ball with a speed \( v \) of \( 6.0 \mathrm{~m} / \mathrm{s} \) strikes a wall at an angle \( \theta \) of \( 30^{\circ} \) and then rebounds with the same speed and angle.

It is in contact with the
wall for \( 10 \mathrm{~ms} \). In unitvector notation, what are the impulse on the ball from the wall
