The graph below shows the relationship between "speed" and "time" for two objects, A and B. How does the acceleration of object A compare to that of object B?

• The acceleration of A is the same as the acceleration of B.

• The acceleration of A is three times the acceleration of B.

• The acceleration of A is one-third the acceleration of B.

• The acceleration of A is twice the acceleration of B.
