Answer:
static coefficient = 0,203 & kinetic coefficient = 0,14
Explanation:
There are two (2) conditions, when the desk is about to move and when the desk is moving. In the attachements you can see the two free body diagram for each condition.
In the first condition, there is no movement and the force is 12 N, in the image we can see the total forces are equal to 0 and by the definition of the friction force we can get the static friction coefficient.
In the second condition there is movement in the direction of the force which is equal to 8 N, again by the definition of the friction force we can get the kinetic friction coefficient. Since the desk is moving with constant velocity there is not acceleration.
Answer: See below
Explanation:
<u>Given:</u>
Mass of the Mercedes-Benz (m) = 1700 kg
Inclination of the road (θ) = 15.0
<em>The free body diagram is shown in figure attached below</em>
<em />
a) The normal force is equal to the cos component of the weight of the car.
b) The static force will be equal to the weight's sin component.
