\( A \) is projected from origin with an initial velocity \( v_{0}=700 \mathrm{~cm} / \mathrm{s} \) in a direction \( 37^{\circ} \) above the horizontal as shown in figure-1.164. Another ball \( B, 300 \mathrm{~cm} \) from origin on a line \( 37^{\circ} \) above the horizontal is released from rest at the instant \( A \) starts. (a) How far will \( B \) have fallen when it is hit by \( A \) ? (b) In what direction \( A \) moving when it hits \( B \) ?
