Which of the following can be inferred from the graph?

a
The object moves at a constant speed.
b
The object is moving along a curved path.
c
The object has a negative acceleration.
d
The object is experiencing acceleration.

The correct answer is: d. The object is experiencing acceleration.

This can be inferred because the graph shows an increasing slope, indicating that the object's velocity is changing over time, which implies the presence of acceleration.
