Answer:
The coefficient of static friction between the puppy and the floor is 0.7273.
Explanation:
The horizontal force applied to move the puppy from a steady state has to be greater than the force of static friction, after it is moving the force needs to be equal to be greater than the force of dynamic friction in order to maintain its movement. The force of static friction is given by:
Where is the static friction force, is the coefficient of static friction and is the normal force. Since there's no angle on the flor the normal force is equal to the weight of the puppy, therefore, , to make the puppy moving we need to use a force of 80 N, therefore, , so we can solve for the coefficient as shown below:
The coefficient of static friction between the puppy and the floor is 0.7273.
The buoyant force of an object which is submerged in water or any fluid is equal to the weight of the fluid displaced by an object.
why? the buoyant force goes up, and the gravitational pull goes down. <span />
Answer:
velocity because it says you are going 3 miles north and velocity is something going a speed in a certian direction
