Use integrals with limits to complete the following. Credit will not be given for integrals without limits. 1. A jet lands on a runway. Between the time the jet touches the ground (t = 0) and when it comes to rest, the jet has a velocity given by v(t) = 160.0 - 2.5 ³. m m . (a) Write down a definite integral that will give you the displacement of the jet between t = 1.0 s and t = 3.0 s. (b) Evaluate the definite integral you wrote out in part (a) to determine the displacement of the jet between t = 1.0 s and t = 3.0 s?

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.]
