Question

A particle moves in a circle with constant speed of 15 m/s . Radius of a circle is 2m . Determine centripetal acceleration. ​

Answer 1

Explanation:

A particle moves in a circle with constant speed of 15 m/s . Radius of a circle is 2m . Determine centripetal

Answer 2

Answer :

• Centripetal acceleration is 112.5 m/s²

Given :

• A particle moves in a circle with constant speed of 15 m/s . Radius of a circle is 2m .

To find :

• Centripetal acceleration

Solution :

Given,

• v = 15m/s
• r = 2m

We know that

• Centripetal acceleration (a) = v²/r

Where,

• v is 15m/s (velocity)
• r is 2m (radius)

↦ a = v²/r

↦ a = 15²/2

↦ a = 15 × 15 / 2

↦ a = 225/2

↦ a = 112.5 m/s².

Hence,

Centripetal acceleration is 112.5 m/s²
