A. Through the direct contact of particles
Answer:
v₁ = 37.5 cm / s
Explanation:
For this exercise we can use that angular and linear velocity are related
v = w r
in the case of the spool the angular velocity for the whole system is constant,
They indicate the linear velocity v₀ = 25.0 cm / s for a radius of r₀ = 1.00 cm,
w = v₀ /r₀
for the outside of the spool r₁ = 1.5 cm
w = v₁ / r₁1
since the angular velocity is the same we set the two expressions equal
v1 =
let's calculate
v₁ =
v₁ = 37.5 cm / s
I think that the answer to that is true hope that helps
Velocity means [ (speed) and (direction) ].
If you're traveling around a curve, then your direction is
always changing. So your velocity is always changing,
even if your speed isn't.
Statements 1, 3, and 5 are true.
