Question

What is Hunter the dog's centripetal acceleration when he runs along a circular path of radius 2.0 meters with a tangential speed of 2.2 meters/second?

Answer 1

Answer:

2.42 m/s^2

Explanation:

r = 2 m, v = 2.2 m / s

The acceleration acting on the dog is centripetal.

The formula for the centripetal acceleration is given by

ac = v^2 / r

ac = (2.2 x 2.2) / 2 = 4.84 / 2 = 2.42 m/s^2

Answer 2

The dogs centripetal acceleration is 2.4 meters/second^2
