A dog is running in a circle around a tree, trying to catch a rabbit. The dog's owner notices the dog completes 4 laps around the tree in 32 seconds and the radius of the dog's circular path is
3 meters. What is the tangential velocity of the dog?

2.35 m/s

Explanation:

Given

Dog completes 4 laps around the tree in  32 seconds

Radius of the circular path is 3 m

Time period for single lap is  

Length of the track is equivalent to the perimeter of the path

Tangential velocity is given by

Thus, the tangential velocity is 2.35 m/s

in physics zero. in muscle fatigue could be high

the maxium height is 34m/s
