Alexandra is attempting to drag her 32.6 kg golden retriever across the wooden floor by applying a horizontal force. What force must she apply to move the dog with a constant speed of 0.95 m/s? The coefficient of friction between the dog and the floor is 0.72

Given values:

The net force will be:

→

Since acceleration,

a = 0

hence,

The force applied by her will be:

→

By putting the values, we get

→    

Thus the above answer is right.

230.26 N

Explanation:

Since the speed is constant, acceleration is zero hence the net force will be given by the product of mass, coefficient of friction and acceleration due to gravity

F=0.72*32.6*9.81=230.26 N

are their multiple choices ?

explanation:

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
