Question

Graham, an alien, shoots an arrow into the air. How long does it take the arrow to hit the ground?

A) 2 seconds
B) 4 seconds
C) 6 seconds
D) 8 seconds

Answer 1

In projectile motion, the time it takes for an object to hit the ground depends on its initial velocity and the height from which it is shot. option D) 8 seconds is the correct answer.

Step-by-step explanation:

Physics: Projectile Motion

To determine how long it takes for an arrow shot by Graham to hit the ground, we need to consider the concept of projectile motion. Projectile motion is the motion of an object thrown or shot into the air, under the influence of gravity.

When an object is shot into the air, it follows a curved path called a parabola. The time it takes for the object to hit the ground depends on its initial velocity and the height from which it is shot.

In this case, we do not have enough information about the initial velocity or the height from which the arrow is shot. Therefore, we cannot determine the exact time it takes for the arrow to hit the ground. The correct answer is D) 8 seconds, as it is not possible to accurately determine the time without additional information.
