• Given:

,

• Mass = 2113 kg

,

• Radius, r = 49 m

,

• Speed, v = 12 m/s

Let's find the centripetal acceleration.

To find the centripetal acceleration, apply the formula:


a=(v^2)/(r)

Where:

a is the centripetal acceleration

v is the speed

r is the radius

Thus, we have:


\begin{gathered} a=(12^2)/(49) \\ \\ a=(144)/(49) \\ \\ a=2.94\text{ m/s} \end{gathered}

Therefore, the centripetal acceleration is 2.94 m/s²

• ANSWER:

2.94 m/s²
