Draw a velocity versus time graph for an object whose constant velocity is 15 m/s and whose position starts at x= 0 when t = 0 Graph the motion for the first 5.0 seconds.
A.) For the motion graphed in the position versus time graph shown above, what is the average velocity in the time interval 1 to 3 seconds?
B.) For the motion graphed in the position versus time graph shown above, what is the average velocity in the time interval 3 to 4 seconds?
C.) For the motion graphed in the position versus time graph shown above, what is the average velocity in the time interval 5 to 6 seconds?
a.When is the particle moving in the positive direction? (Enter your answer using interval notation.)
b.Draw a diagram to illustrate the motion of the particle and use it to find the total distance (in ft) traveled during the first 6 seconds.
c.When is the particle speeding up?When is the particle slowing down? (answer in interval notation.)
Explain why we only consider one dimensional motion when using a single motion sensor. Based on the definition of velocity, describe what you should observe in the velocity vs. time graph if you were measuring a stationary, distant object and you suddenly slid and object into the beam from the side [hint: think about the behavior of the position graph in this case.]
