Santiago is on a skateboard and has an initial velocity of (-0.44 \(m/s\)) \(\hat{\imath}\) relative to Maya who is at rest with respect to the earth. Just as they are gliding past Maya, Santiago throws a ball in the positive \(x\)-direction from a height of 4.05 m. According to Santiago, the ball has an initial velocity of (3.98 \(m/s\)) \(\hat{\imath}\).
