Question

A zoology graduate student is provided with a bow and an arrow tipped with a syringe of sedative and is 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 100 m. a truculent rhino suddenly charges straight toward him at if he fully draws his bow and aims 20° above the horizontal, how far away should the rhino be when the student releases the arrow?

Answer 1

The student should release the arrow when the rhino is 100 m away.

Step-by-step explanation:

To find the distance at which the student should release the arrow, we can use the concept of projectile motion.

When fully drawn and aimed 45° above the horizontal, the range of the bow is 100 m. This means that the arrow travels 100 m horizontally when it is released.

Now, when the student aims 20° above the horizontal, we need to find the horizontal distance traveled by the arrow to determine how far away the rhino should be.

Since the horizontal component of the velocity remains the same, the arrow will still travel 100 m horizontally. Therefore, the rhino should be 100 m away from the student when the arrow is released.
