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

i would think form in reponse to tensional forces

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
