## Motion in Two Dimensions ANSWERS TO QUESTIONS

But, we have not developed a specific equation that relates acceleration and displacement. In this section, we look at some convenient equations for kinematic relationships, starting from the definitions of displacement, velocity, and acceleration. We first investigate a single object in motion, called single-body motion. Then we investigate the motion of two objects, called two-body pursuit problems. First, let us make some simplifications in notation. Taking the initial time to be zero, as if time is measured with a stopwatch, is a great simplification. When initial time is taken to be zero, we use the subscript 0 to denote initial values of position and velocity.

How high does the object get before beginning its descent? The velocity must be broken down into x horizontal and y vertical components. We can use the y component to find how high the object gets. To find vertical velocity, v y , use. Next we find how long it takes to reach the top of its trajectory using. Finally, find how high the object goes with. How far away does the object land?

Note that if the initial velocity is in a direction that is along neither axis, one must first break up the initial velocity into its components. In the last few chapters we have considered the motion of a particle that moves along a straight line with constant acceleration. In such a case, the velocity and the acceleration are always directed along one and the same line, the line on which the particle moves. Here we continue to restrict ourselves to cases involving constant acceleration constant in both magnitude and direction but lift the restriction that the velocity and the acceleration be directed along one and the same line. If the velocity of the particle at time zero is not collinear with the acceleration, then the velocity will never be collinear with the acceleration and the particle will move along a curved path. The curved path will be confined to the plane that contains both the initial velocity vector and the acceleration vector, and in that plane, the trajectory will be a parabola. The trajectory is just the path of the particle.

The negative solutions are not relavent to this problem. Page MFMcGraw - PHY Chap_04H - 2D & 3D - Revised 1/3/.
