A dog is tied to a post in the ground by Alicia violet of 2 m if the dog runs at a concert velocity of 4M/S and a circle around the post find the dogss centripetal acceleration

Centripetal acceleration = 8m/s²

Explanation:

Given the following data;

Radius, r = 2m

Velocity = 4m/s

To find the centripetal acceleration;

Centripetal acceleration = V²/r

Substituting into the equation, we have;

Centripetal acceleration = 4²/2

Centripetal acceleration = 16/2

Centripetal acceleration = 8m/s²

Therefore, the dog's centripetal acceleration is 8 meters per seconds square.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
