Question

18 use the graph to answer the following question. motion of a remote control car which two points did the car have the greatest speed? a points b and c b points a and b c points a and d d points c and d

Explanation:

Step1: Recall speed - position graph relationship

Speed is the slope of the position - time graph. Steeper the slope, greater the speed.

Step2: Analyze slopes between points

Between A and B, slope is positive and moderate. Between B and C, slope is 0 (constant position, speed = 0). Between C and D, slope is negative and relatively steep. Between A and D, the overall slope is less steep compared to C - D segment.

Answer:

D. points C and D
