Question

The graph below shows the relationship between speed and time for two objects, A and B. Compare with the acceleration of object B, the acceleration of object A is

A. Greater
B. The same
C. Lesser
D. One-third as less

Answer 1

Answer:

A) greater

Explanation:

acceleration is calculated by dividing velocity over time..so by calculating, you find acceleration of A is greater than that of B

Answer 2

The acceleration of object A is greater than the acceleration of object B.

Acceleration is the slope of a velocity - time graph. The object that will have a greater acceleration is the object that has a larger slope.

If we observe the two graphs carefully, we will observe that the slope of the graph showing the motion of object A is larger than the slope of the graph showing the motion of object B hence, the acceleration of object A is greater than the acceleration of object B.
