A passenger in the rear seat of a car moving at a

steady speed is at rest relative to

*the side of the road
a pedestrian on the corner ahead
the front seat of the car
the wheels of the car

A person walks 1 mile every day for excercise, leaving
her porch at 9:00 a.m. and returning at 9:25 a.m.
What is the total displacement of her daily walk?

1 mile
*0
25 minutes
none of the above

A person drives north 6 blocks, turns west, and
then drives 6 blocks. The driver then turns south
and drives 6 blocks. How could the driver have made
the distance shorter while maintaining the same
displacement?

*by driving west 6 blocks from the starting point
by driving north 4 blocks and west 7 blocks
by driving south 6 blocks from the starting point
by driving back to the starting point by the same route

A ball is rolled uphill a distance of 5 meters before it
slows, stops, and begins to roll back. The ball rolls
downhill 9 meters before coming to rest against a tree.
What is the magnitude of the ball's displacement?

4meters
*9meters
14meters
45meters

Thank You :) I appreciate it! ^_^

Answer to the first question is: the front seat of the car.

Second answer is: 0
Third answer is: by driving west 6 blocks from the starting point
Fourth answer is: 4 meters

Man I need some help too!

100% twinwin and I love being a cheater.

TwinWin got it right. 100% correct.

Thanks TwinWin

twinwin 100% yay

1. Displacement is the difference between the starting point and the end. In this case, they are the same,Therefore, the displacement is 0.

2. Ans. is A.

3. 9 - 5 = 4 meters beyond starting point. Disp. = 4 meters.
Ans. is A.

A passenger in the rear seat of a car moving at a steady speed is at rest relative to the *the side of the road, the wheels of the car, and the front seat of the car. This is because the passenger is moving at the same speed as the car and is not changing their position relative to these objects.

In the case of the person walking 1 mile every day for exercise, the total displacement is 0. Displacement is a measurement of the change in position, and since the person ends up back at their starting point, there is no net change in position. So, the correct answer is *0.

To make the distance shorter while maintaining the same displacement in the given scenario of driving north 6 blocks, turning west and driving 6 blocks, and then turning south and driving 6 blocks, the driver could have driven west 6 blocks from the starting point. By doing so, the driver would have eliminated the additional distance traveled to the north and then south, while still maintaining the same displacement.

For the ball rolled uphill a distance of 5 meters and then rolling downhill 9 meters before coming to rest against a tree, the magnitude of the ball's displacement is 9 meters. Displacement is a vector quantity that considers both magnitude (distance) and direction. In this case, the ball traveled uphill 5 meters and then downhill 9 meters, which results in a net displacement of 9 meters downhill.

You're welcome! If you have any more questions, feel free to ask.
