Answer:
they are similar cuz it resembles a "z" pattern. The angles are so the same.
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.
I poooped myself there is brown stuff all over the place
19/38 is not reduces. Numerator and denominator can be divided by 19.
