An astronaut is rotated in a horizontal centrifuge at a radius of 5.0 m. (a) What is the astronaut’s speed if the centripetal ac
sergeinik [125]

Explanation:

Given that,

Radius of circular path, r = 5 m

Centripetal acceleration, a=7g\ m/s^2

(a) Let v is the astronaut’s speed. The formula for the centripetal acceleration is given by :

a=\dfrac{v^2}{r}

v=\sqrt{ar}

v=\sqrt{7\times 9.8\times 5}

v = 18.5 m/s

(b) Let T denotes the time period. It is given by :

T=\dfrac{2\pi r}{v}

T=\dfrac{2\pi \times 5}{18.5}

T = 1.69 s

Let N is the number of revolutions. So,

N=\dfrac{60}{1.69}=35.5\ rev/min

So, the number of revolutions per minute is 35.5

(c) T = 1.69 seconds

Hence, this is the required solution.
