Two-dimensional motion Consider the motion of the following objects. Assume the x-axis is horizontal, the positive y-axis is vertical, the ground is horizontal, and only the gravitational force acts on the object. a. Find the velocity and position vectors , for t ≥ 0. b. Graph the trajectory. c. Determine the time of flight and range of the object. d. Determine the maximum height of the object. 38. A golf ball has an initial position 〈 x 0 , y 0 〉 = 〈0, 0〉 when it is hit at an angle of 30° with an initial speed of 150 ft/s.

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
Force with 800 N and 400 N are acting on a machine part at 30° and 60°, respectively with the positive x axis
