A1.8 × 10^3 kg car is parked on a hill on a 15° incline. a 1.25 × 10^4 n frictional force holds the car in place. what's the coefficient of static friction

The coefficient of static friction = 0.73

Explanation:

In order to solve this problem we must make a free body diagram of the car on the inclined surface and the forces acting on it. We must bear in mind that there is no movement and therefore all the forces summations on the y axis should be equal to zero.

The friction force is equal to the product of the normal force multiplied by the coefficient of friction.

There is an attached image with the forces acting and the equations deducted.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
