A mass of 0.84 kg is moved by a force that is always directed towards the North but its magnitude changes quadratically with time. The magnitude of the force is F=(9 N/s^2)t^2. The y−axis points towards the North.  What is the change in velocity in m/s between t=0 and t=1.6 what is the change in the y−coordinates in meters of the object between initial time t=0 s and t=1.6s with initial velocity 17.1 m/s directed North (same direction of force)
