A ball travels around a roulette wheel with a radius of 0.4 m at a tangential velocity of 1.1 m/s. What is the period of the ball as it travels around the wheel?

Respuesta :

Answer:

T = 2.28 s

Explanation:

Given that,

The radius of the wheel, r = 0.4 m

The tangential velocity of the wheel, v = 1.1 m/s

We need to find the period of the ball as it travels around the wheel. Let it is T. We know that, the tangential speed is given by :

[tex]v=\dfrac{2\pi r}{T}\\\\T=\dfrac{2\pi r}{v}\\\\T=\dfrac{2\pi \times 0.4}{1.1}\\\\T=2.28\ s[/tex]

So, the period of the ball is equal to 2.28 s.
