MasteringPhysics: Kinematics 1-Google Chrome tps://session.masteringphysics.com/myct/itemView?assignmentProblem YS211-Spring2016-UTM E ics1What Velocity vs. Time Graphs Can Tell You A common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time t is plotted on the horizontal axis and velocity u on the vertical axis. Note that by definition velocity and acceleration are vector quantities. In straight-line motion, however, these vectors have only a single nonzero component in the direction of motion. Thus, in this problem, we will call v the velocity and a the acceleration, even though they are Here is a plot of velocit Refer to this plot to ans Part A What is the initial v Express your ans Figure 1 ·011 U(m/s) zo = 2.0 1.5 1.0 Submit Hint Part B What is the total dis 0.5 Express your answ (s) 10 20 30 4050 na.

Explanation / Answer

A) Initial velocity when t = 0, V0 = 0.5 m/s
B) Total distance travelled = area under the v-t curve = 0.5*20*2.5 + 0.5*2*50 = 75 m.
C) average acceleration = (vf-vi)/delta t = 0.5/45= 0.011 m/s^2.
D) Instantaneous Acceleration = slope of v-t curve, at t = 45 sec, a = -0.2 m/s^2
E) Graph B explains the a-t correctly as the acceleration = slope of v-t curve.
