Question

the picture and graph below show the movements of a car on a straight road. a list of five positions is below. drag and drop each explanation to the correct location to describe the cars movement. l m n o p car moving at fastest reverse speed car stationary car moving at slowest reverse speed car moving at fastest forward speed car moving at slowest forward speed

Explanation:

Step1: Recall speed - slope relationship

The slope of the position - time graph represents the speed of the car. A steeper positive slope means a faster forward speed, a steeper negative slope means a faster reverse speed, and a zero - slope means the car is stationary.

Step2: Analyze segment L

The slope of segment L is positive and relatively steep compared to other forward - moving segments, so the car is moving at the fastest forward speed on segment L.

Step3: Analyze segment M

The slope of segment M is positive but less steep than L, so the car is moving at the slowest forward speed on segment M.

Step4: Analyze segment N

The slope of segment N is zero, so the car is stationary on segment N.

Step5: Analyze segment O

The slope of segment O is negative and relatively steep, so the car is moving at the fastest reverse speed on segment O.

Step6: Analyze segment P

The slope of segment P is negative but less steep than O, so the car is moving at the slowest reverse speed on segment P.

Answer:

L: Car moving at fastest forward speed
M: Car moving at slowest forward speed
N: Car stationary
O: Car moving at fastest reverse speed
P: Car moving at slowest reverse speed
