The estimate of the problem would be 1/4 because 6/8- 1/2 you would get 1/4.
~Good Luck!~
You either find the gradient or distance and if there are equal, therefore the opp are equal
S= 13/5 is the answer
I hope it’s help u !
Answer: The sphere is 0.002548 cm travel up the plane.
Step-by-step explanation:
Since we have given that
Inclination angle = 30°
Translational speed = 0.25 m/s
As we know that

and
Length of solid sphere is given by

So, it becomes,

And 
So, it becomes,

Hence, the sphere is 0.002548 cm travel up the plane.
