A Flying Arrow

Mateo and Savannah watch an arrow fly past them. The arrow has mass \(m = \) 0.282 \(kg\). Mateo is sitting on a stump and sees the arrow move with velocity \(v_x = \) \(m/s\). Mateo also notes that Savannah is riding a horse and measures Savannah’s position to be \(x(t) = \) 7.61 \(m\) + (18.5 \(m/s\)) \(t\), where \(t\) is time measured in seconds.
