Solve the following question given below:
Question: A zoology graduate student is provided with a bow and an arrow tipped with a syring of sedative and assigned to measure the temperature of a black rhinoceros (Diceros bicornis). The range of his bow when it is fully drawn and aimed 45 above the horizontal is 100m. A truculent rhino suddenly charges straight toward him at km/h. If he fully draws his bow and aims 20 above the horizontal.
Part A: How far away should the rhino be when the student releases the arrow?
