You are asked to find the depth to which the ball is submerged when floating in water.
The equation that gives the depth x to which the ball is submerged under water is given by
Use the secant method of finding roots of equations to find the depth x to which the ball is submerged under water.
Conduct three iterations to estimate the root of the above equation.
Find the absolute relative approximate error and the number of significant digits at least correct at the end of each iteration.
The number of significant digits at least correct is 0, as you need an absolute relative approximate error of 5% or less for one significant digit to be correct in your result.
