The very first option is correct, as any other answer is either incorrect in terms of optics or does not stop you from seeing the apple.
Answer:
acceleration will be tripled.
Explanation:
We know, when an object is performing Simple harmonic motion, the force
experience by it is directly proportional to its displacement from its mean position.
Also, F = ma , therefore, acceleration is also proportional to its displacement .
Now, F = kx
Therefore, 
If we triple the displacement i.e, 3x.
Acceleration 
Therefore, acceleration is also tripled.
Hence, this is the required solution.
Answer:
The distance traveled will be 156.0 m
Explanation:
Please, see the attached figure 1 for a description of the problem.
The distance traveled by the prey is the magnitude of the vector "r" (see figure).
If the components of "r" are "rx" (horizontal component) and "ry" (vertical component), its magnitude will be:

We already know the vertical component of r, ry, because the prey falls from an altitude of 156 m (see figure). Then ry = 156 m
To find the value of rx we will use the function that describes the trajectory of the prey (see figure 2):
y = -39 · x² + 156
When the prey hits the ground, the height is 0 (y = 0). rx will be the value of x for which y = 0.
0 = -39 · x² + 156
-156/-39 = x²
x = 2.0 m
Then r = (2.0 m, -156.0 m)
The distance traveled will be:

Answer:
Vectors and arrows.
Explanation:
Mathematically speaking, forces are represented by vectors, which have magnitude and direction. Graphically speaking, vectors are represented by arrows.
