motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average speed, vavg, during this period, in meters per second? 2. What was the motorcycle's displacement in the northern direction during this period, in meters?
