Question

a particle moves in a circle radius 30 cm with a constant speed 6 m / s . find its centripital acceleration.​

Answer 1

Answer:

666 77 the following extract and

Answer 2

$\:\:\:\: \large \underline {\sf{Given\::}}$

• Radius ( r ) = 30 cm = 0.3 m

• Speed ( v ) = 6 m/s

$\:\:\:\: \large \underline {\sf{To\:Find\::}}$

• Centripetal acceleration , $\sf {a}_{c}$

$\:\:\:\: \large \underline {\sf{Solution\::}}$

$\underline{\boxed{\sf{Formula\:used\:=\: \dfrac{{v}^{2}}{r}}}}$

=> $\sf\dfrac{{v}^{2}}{r}$

=> $\sf\dfrac{{6}^{2}}{0.3}$

=> $\sf\dfrac{36}{0.3}$

=> $\sf 120 \:m/s$

$\:\:\:\: \underline {\sf{\red{Centripetal\: acceleration\:,\: {a}_{c} \:=\:120\: m/s}}}$
