Solution:

To find the maximum displacement of the ball along the x-direction when the displacement along the y-direction is zero, we need to set the equation equal to zero and solve for x. Let's break down the problem step by step.

Step 1: Set the equation equal to zero.
y = x/√3 - 3gx^2/8

Since we want to find the maximum displacement of x when y is zero, we can set y equal to zero and solve for x.

0 = x/√3 - 3gx^2/8

Step 2: Simplify the equation.
To simplify the equation, we can multiply the entire equation by 8 to eliminate the fractions.

0 = 8(x/√3) - 8(3gx^2/8)

0 = 8x/√3 - 3gx^2

Step 3: Rearrange the equation.
To make the equation easier to work with, let's rearrange it.

3gx^2 = 8x/√3

Step 4: Square both sides of the equation.
To eliminate the square root, we can square both sides of the equation.

(3gx^2)^2 = (8x/√3)^2

9g^2x^4 = 64x^2/3

Step 5: Simplify the equation.
To simplify the equation, we can multiply both sides by 3 to eliminate the fraction.

27g^2x^4 = 64x^2

Step 6: Solve for x.
To solve for x, we can divide both sides of the equation by x^2.

27g^2x^2 = 64

x^2 = 64 / 27g^2

x = ±√(64 / 27g^2)

Step 7: Determine the maximum displacement.
Since we are looking for the maximum displacement along the x-direction, we only consider the positive value of x.

Therefore, the maximum displacement of the ball along the x-direction for which the displacement along the y-direction is zero is given by:

x = √(64 / 27g^2)

Conclusion:
The maximum displacement of the ball along the x-direction for which the displacement along the y-direction is zero is √(64 / 27g^2).
