Suppose that the graph of the velocity function of a particle is as shown in the figure, where t is measured in seconds.
0
When is the particle traveling forward (in the positive direction)? (Enter your answer using interval notation.)
When is it traveling backward? (Enter your answer using interval notation.)
What is happening when 5 < t < 7?.
The velocity is zero and the particle is not moving.
The velocity is decreasing and the particle is slowing down.
The velocity is constant and the particle is moving at a steady speed backward.
The velocity is constant and the particle is moving at a steady speed forward.
The velocity is increasing and the particle is speeding up.
