An object is moving in the horizontal axis with a velocity of v, = (4i + 1j)". Its initial position is r, = (10i – 4j) m. After moving with a constant acceleration for 20 seconds, its velocity is v = (20i – 5j) Solve for the following: a. The components of the acceleration. b. The direction of the acceleration with respect to the x-axis. c. The position of the object at 25 seconds and its direction.
