What are the weight and normal force of a stationary car on a sloped road?

In summary, a stationary car with a weight W is on a road sloping at 30 degrees to the horizontal. The frictional force on the car is 4000 N acting up the road BC. The normal contact force R of the road surface on the car is unknown. The vector diagram should show the road sloping down to the right, with the frictional force pointing back up the road in an upward and leftward direction.

What is
(a) the weight W
(b) the normal contact force R of the road surface on the car?

What exactly are you stuck on? You're going to need to show evidence of having done stuff, as people aren't going to do your homework for you!

Well...the first part. I can't get the vector diagram right. Where do I put 4000 N to start with?

Draw your picture with the road sloping down to the right, say. Then the frictional force points back up the road, up and to the left.
 

FAQ: What are the weight and normal force of a stationary car on a sloped road?

What is frictional force on a car?

Frictional force on a car is the force that opposes the motion of the car. It is caused by the interaction between the tires of the car and the surface of the road.

What factors affect the frictional force on a car?

The frictional force on a car is affected by factors such as the weight of the car, the type and condition of the tires, and the surface of the road. Other factors include the speed and direction of the car, and external forces like wind or water.

How does frictional force impact the performance of a car?

Frictional force can impact the performance of a car in several ways. It can affect the acceleration, braking, and handling of the car. Too much friction can cause the car to slow down or lose control, while too little friction can reduce the car's ability to grip the road.

How can frictional force be reduced on a car?

Frictional force can be reduced on a car by using smooth and well-maintained tires, reducing the weight of the car, and using materials that reduce friction, such as lubricants. Additionally, driving at a steady speed and avoiding sudden changes in direction can also help reduce frictional force on a car.

Can frictional force be beneficial for a car?

Yes, frictional force can be beneficial for a car in certain situations. For example, friction between the tires and the road allows the car to grip the road and stay in control while turning or braking. Additionally, frictional force can help slow down the car and bring it to a stop.
