Question

A 12kg object undergoes circular motion with a radius of 4 m and a speed of 18m/s. What is the centripetal acceleration of the object ?

Answer 1

a = 16 m/s²

Step-by-step explanation:

The mass of the object, m = 200 kg

The radius of the circular motion, r = 4 m

The speed of the object, v = 18 m/s

The centripetal acceleration is given by the relation,

a = v²/r

Substituting the given values,

a = 18 / 4

= 16 m/s²

Hence, the centripetal acceleration of the object is, a = 16 m/s²
