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. 41. A projectile is launched from a platform 20 ft above the ground at an angle of 60° above the horizontal with a speed of 250 ft/s. Assume the origin is at the base of the platform.

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.
