A common graphical representation of motion along a straight line is the u vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this Figure U(m/s) 2.0 1.5 1.0 0.5 0 10 20 30 40 50 1 of 1 t(s) (Figure 1) is a plot of velocity versus time for a particle that travels along a straight line with a varying velocity. Refer to this plot to the following questions. Part A What is the initial velocity of the particle, vo? Express your answer in meters per second. View Available Hint(s) V| Vo = Submit ? m/s
