Question

Problem 7. Below you are supplied a position versus time graph. Draw velocity versus time and acceleration versus time graphs consistent with this position versus time graph. Assume that this is one dimensional motion along the x axis, that you are standing on the origin (x = 0) with positive x off to your right and negative x off to your left. Describe the motion of the object in everyday terms without using the words velocity, acceleration, slope, positive or negative. (The easy way to start to do this is to divide the position versus time graph into 4 equal sections and describe what the slope does in each in terms of sign and tendency.) (12 points) -X + a

Answer 1

It describes the to and fro motion of an object with increasing and decreasing velocity. Motion of pendulum is such type of motion.

Slope zero +x slope decreasing Slope of distance time graph gives velocity -V dt -X zero velocity Slope of velocity time graph gives acceleration 'slope zero а zero acceleration t
