A Flying Arrow

Aliyah and Ximena watch an arrow fly past them. The arrow has mass \(m = \) 0.325 \(kg\). Aliyah is sitting on a stump and sees the arrow move with velocity \(v_x = \) -76.2 \(m/s\). Aliyah also notes that Ximena is riding a horse and measures Ximena’s position to be \(x(t) = \) 6.67 \(m\) + (16.2 \(m/s\)) \(t\), where \(t\) is time measured in seconds.
