A Skateboarder and an Observer#
Lorenzo is on a skateboard and has an initial velocity of (-0.584 \(m/s\)) \(\hat{\imath}\) relative to Santiago who is at rest with respect to the earth. Just as they are gliding past Santiago, Lorenzo throws a ball in the positive \(x\)-direction from a height of 4.51 m. According to Lorenzo, the ball has an initial velocity of (4.0 \(m/s\)) \(\hat{\imath}\).
