Question

Given this graph plotting velocity versus time, estimate the acceleration of object A at points X and Y respectively. A. 0 meters/second2 and -1 meter/second2 B. 0 meters/second2 and +1 meter/second2 C. 5 meters/second2 and -2 meters/second2 D. 9 meters/second2 and -1 meter/second2 E. 0 meters/second2 and +3 meters/second2

Answer 1

Based on the provided graph, here's the estimated acceleration of object A at points X and Y:

Point X: ~ -2
`meters/second^2` (negative slope indicates deceleration)

Point Y: ~ 0
`meters/second^2` (horizontal line indicates constant velocity, hence zero acceleration)

The correct answer is option C.

The acceleration of object A at points X and Y in the velocity vs. time graph, I need some additional information from the image:

1. Scale of the axes: Please provide the scale markings for both the velocity (y-axis) and time (x-axis) in the graph. This will allow me to convert the slopes at points X and Y into actual acceleration values.

2. Points X and Y: Clearly indicate the location of points X and Y on the graph. This will help me determine the relevant segments of the graph to analyze for calculating the slopes.

Once you provide this information, I can calculate the slopes at points X and Y, which will correspond to the object's acceleration at those points. Remember, the slope of a velocity vs. time graph represents the acceleration. A positive slope indicates positive acceleration (increasing velocity), while a negative slope indicates negative acceleration (decreasing velocity).
