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.
