Answer:
Explanation:
Given that,
Small wheel applied force
F₁ = 50N
Small wheel radius
r₁ = 18cm
Bigger wheel radius.
r₂ = 29cm
Bigger wheel applied force
F₂ =?
Since the combination of those forces did not cause the wheel to rotate,
Then, Στ = 0
F₁•r₁ —F₂•r₂ =
50×18 — 29F₂ = 0
900 = 29F₂
F₂ = 900 / 29
F₂ = 31.03 N
The pulling force applied at the larger wheel is 31.03N
80 (km / hour) * (1,000 meters/ km) * (1 hour/ 60 minutes) * (1 minute / 60 seconds) = 22.2 meters / second
