Answer:

\huge\boxed{\sf a_{c} = 15.6\ m/s^2}

Explanation:

<u>Given Data:</u>

Radius = r = 40 m

Speed = v = 25 m/s

<u>Required:</u>

Centripetal Acceleration = \sf a_{c} = ?

<u>Formula:</u>

\sf a_{c} = \frac{v^2 }{r}

<u>Solution:</u>

\sf a_{c} = \frac{v^2}{r} \\\\a_{c} = \frac{(25)^2}{40} \\\\a_{c} = \frac{625}{40} \\\\a_{c} = 15.6 m/s^2\\\\\rule[225]{225}{2}

Hope this helped!

What are three foods that would be considered good energy sources?
jok3333 [9.3K]
Almonds, like many nuts, are one of the best plant sources of protein. Protein will help regulate your blood sugar and keep your energy level stable throughout the day. Oats contain the energizing and stress-lowering B vitamin family, which helps transform carbs into usable energy. Water, without water, your body cannot generate energy.
