and 4) (just in case) science holds pier review, pseudoscience does not
Answer:

Answer:
The force each one experienced
Explanation:
Hope this helps :)
M*g*sin20-f=m*a
<span>and the rotational frame </span>
<span>f*r=I*a/r </span>
<span>where f is the force of friction, a is the translational acceleration and I is the moment of inertia of the sphere </span>
<span>combine and solve for f </span>
<span>a=g*sin20-f/m </span>
<span>and </span>
<span>f*r^2/I=g*sin20-f/m </span>
<span>or </span>
<span>f=g*sin20/(r^2/I+1/m) </span>
<span>I=2*m*r^2/5 </span>
<span>therefore </span>
<span>f=2*m*g*sin20/7</span>
