Final answer:
The velocity of a flower pot when it hits the ground after falling from an 8.0 m high window sill is 12.5 m/s, according to the kinematic equation for a free-falling object.
Step-by-step explanation:
To find the velocity the flower pot has when it hits the ground, we use the kinematic equation for a free-falling object, which is:
v = √(2gh), where v is the final velocity, g is the acceleration due to gravity (9.8 m/s²), and h is the height.
For a flower pot falling from an 8.0 m high window sill, the calculation would be:
v = √(2 * 9.8 m/s² * 8.0 m)
v = √(156.8 m²/s²)
v = 12.5 m/s
Since the question is about the magnitude of velocity and doesn't specify direction, the negative sign used to indicate direction in physics is not needed here. Thus, the correct answer is Option B: 12.5 m/s.
