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.

Answer:
13.01 d -2.65
Step-by-step explanation:
3.26d + 9.75d - 2.65
Combine like terms
3.26d + 9.75d          - 2.65
13.01 d                     -2.65
