Question

02. Passengers on a carnival ride move at constant speed in a horizontal circle of radius 5.Om.making
a complete circle in 4.0s what is their acceleration?


​

Answer 1

Answer:

Centripetal acceleration of the passengers is 12.34 m/s/s

Explanation:

As we know that when object is in uniform circular motion then its acceleration is towards the center of the circle and it is known as centripetal acceleration

Here we know that the time period of the motion is given as

$T = 4 s$

so the angular speed is given as

$\omega = \frac{2\pi}{T}$

$\omega = 1.57 rad/s$

now the centripetal acceleration is given as

$a_c = \omega^2 R$

$a_c = (1.57)^2 \times 5$

$a_c = 12.34 m/s^2$
