An owl is carrying a mouse to the chicks in its nest. Its position at that time is 4.00 m west and 12.0 m above the center of the 30.0 cm diameter nest. The owl is flying east at 3.50 m/s at an angle 30.0º below the horizontal when it accidentally drops the mouse. Is the owl lucky enough to have the mouse hit the nest? To answer this question, calculate the horizontal position of the mouse when it has fallen 12.0 m.

The horizontal position of the mouse is approximately:
a) 2.0 m east
b) 4.0 m east
c) 6.0 m east
d) 8.0 m east

Final answer:

Calculating the horizontal velocity of the owl and the time it takes for the mouse to fall, the horizontal position of the mouse when it hits the ground is approximately 0.72 m east of the nest center. Since this distance is larger than half the nest's diameter, the owl is not lucky enough; the mouse will miss the nest.

Step-by-step explanation:

The question involves calculating the horizontal position of the mouse when it has fallen 12.0 m to determine if it hits the nest. As the owl is flying east at a velocity of 3.50 m/s, we will calculate the horizontal component of this velocity. To do so, we use the cosine component because the owl is flying at a 30.0° angle below the horizontal, resulting in a horizontal velocity (vx) of:

vx = vtotal × cos(θ)
vx = 3.50 m/s × cos(30.0°)
vx ≈ 3.03 m/s

Now, we use the kinematic equation for free fall to determine the time (t) it takes for the mouse to fall 12.0 m.

s = ½gt² → t = √(2s/g)
t = √(2 × 12.0 m / 9.81 m/s²)
t ≈ 1.56 s

Finally, we can find the displacement in the horizontal direction:

Δx = vx × tΔx = 3.03 m/s × 1.56 sΔx ≈ 4.72 m east

The mouse was initially 4.00 m west of the nest, so we add the displacement eastward. Hence, the horizontal position of the mouse when it has fallen 12.0 m:

horizontal position = initial position + displacementhorizontal position = -4.00 m + 4.72 mhorizontal position ≈ 0.72 m east

Since the nest diameter is 30.0 cm (0.3 m) and the horizontal position of the mouse is 0.72 m east, the mouse will miss the nest.
