Explanation:
Answer:
a) Alf travels a quarter of the distance of Beth
b) linear velocity of Beth is 4 times greater than the linear velocity of Alf
Explanation:
This is an exercise that we can solve using the angular kinematic relations and its relation to the linear scientific one
s = θ r
v = ω r
the distance relationship between the two musicians is
if alf is at a distance r₁ = R₀ from the center of the curve
Beth has a distance r₂ = 4 R₀
a) ask for the distance traveled by Alf
Let's find the angle that Beth travels (Musician 2)
θ = s₂ / r₂
the angle traveled is the same for the two musician, the angle for Alf is
θ = s₁ / r₁
s₂ /4R₀ = s₁ /R₀
s₁ = s₂ / 4
therefore Alf travels a quarter of the distance of Beth
b) Beth's linear velocity
look for the angular velocity that is the same for the two musicians
w = v₁ / r₁
w = v₂ / r₂
we equalize
v₁ / r₁ = v₂ / r₂
v₁/R₀ = v₂/4R₀
v₂ = 4 v₁
therefore the linear velocity of Beth is 4 times greater than the linear velocity of Alf
