WebProblem 20 Medium Difficulty For the motion plotted in Fig. 2.15, estimate (a) the greatest velocity in the positive x -direction, (b) the greatest velocity in the negative x -direction, ( c) any times when the object is instantaneously at rest, and (d) the average velocity over the interval shown. FIGURE CAN'T COPY Answer a) 3 m / s b) 1.8 m / s WebThe velocity as the rock reaches the ground will be greater than the initial velocity. Just try substituting values to test this out. v_f = v_i + at v_f = 15m/s - 5m/s^2 (10s) v_f = 15m/s - 50m/s v_f = -35m/s speed_f = v_f speed_f = -35m/s speed_f = 35m/s Therefore, speed_f > speed_i.
