1. The velocity v of a particle moving on the horizontal axis is given by a function of time t as: v = 4 – 3t2 where v is in meters per second and t is in seconds. At time t = 0 s, the particle is at x = 0 meters. Consider the direction to the right as the positive x direction. Which of the following is true about the particle at time t = 2.0 s? It is at the right of its initial position and is slowing down. It is at the right of its initial position and is speeding up. It is at the left of its initial position and is speeding up. It is at its initial position and is speeding up.

Question
1. The velocity v of a particle moving on the horizontal axis is given by a function of time t as:
v = 4 – 3t?
where v is in meters per second and t is in seconds. At time t = 0 s, the particle is at x
0 meters. Consider the direction to the
right as the positive x direction.
Which of the following is true about the particle at time t = 2.0 s?
It is at the right of its initial position and is slowing down.
O It is at the right of its initial position and is speeding up.
It is at the left of its initial position and is speeding up.
It is at its initial position and is speeding up.
