A motorcyclist is riding along at a speed of 16i+0j m/s in wellington when he is hit by a sudden transverse gust of wind. The gust of wind applies a transverse force (in the j direction) on the rider such that the acceleration is 0.9"e-0.4'tj [m/s]. What is i component of the velocity after 4.25 seconds? [m/s] What is the j component of the velocity after 4.25 seconds? [m/s] What is the radius of curvature that the rider follows at t=0 seconds? [m]
