An object is moving at constant velocity of +4.2m/s î (in the +x-axis direction) and approaches the origin. When it reaches the origin, a constant acceleration starts with a = -2.1m/s2 + 3.1m/s 23.
(6 questions) Find each of the following: the magnitude and direction of the displacement (from starting position), the magnitude and direction of
the (instantaneous) velocity, and the magnitude and direction of the acceleration at t= 2.0, and 4.0 seconds.
1. The magnitude and direction of the displacement at t = 2.0 seconds is
I
m (2 significant digits) at a standard
position angle of
degrees (to the nearest degree).
