Question

Centripetal acceleration of a cyclist completing 7 rounds in a minute along a circular track of radius 5 m with
a constant speed, is
(1) 2.7 m/s2
(2) 4 m/s2
(3) 3.78 m/s2
(4) 6 m/s2​

Answer 1

Answer:

1

Explanation:

Answer 2

Answer:

The centripetal acceleration is 2.7 m/s².

(1) is correct option.

Explanation:

Given that,

Rotation = 7 in a minute

Radius = 5 m

We need to calculate the centripetal acceleration

Using formula of centripetal acceleration

$\alpha=\omega^2 r$

Where, $\omega$ = angular velocity

r = radius

Put the value into the formula

$\alpha=(\dfrac{7\times2\pi}{60})^2\times5$

$\alpha=2.7\ m/s^2$

Hence, The centripetal acceleration is 2.7 m/s².
