Problem

Which of the following mathematical expressions matches the velocity-time graph shown at right? a. v(t) = (-2 m/s\mathsf{m/s}) t + (3 m/s\mathsf{m/s}) b. v(t) = (1.25 m/s2\mathsf{m/s^2}) t + (-3 m/s\mathsf{m/s}) c. v(t) = (2 m/s2\mathsf{m/s^2}) + (-3 m/s\mathsf{m/s}) d. v(t) = (-2 m/s2\mathsf{m/s^2}) t + (3 m/s\mathsf{m/s}) e. v(t) = (-3 m/s\mathsf{m/s}) t + (2 m/s\mathsf{m/s}) [Figure: Velocity-time graph referenced but not shown]
