Question
This question has to do with kinematics graphing. I CAN NOT REPRODUCE THE GRAPH BUT hope that some help can be given to me with this question.
The position versus time for a certain object moving along the x-axis. The object's initial position is -2 m. Find the instantaneous velocity at 2 s. Answer in m/s

At time zero, position -2. The rest depends on the velocity. Just compute postion based on
x=xi + v*time
instantaneous velocity is the slope of the position vs time at t=2.
