PHYS 204A Midterm: PHYS 204A Chico State Exam1 Fall 13s
Document Summary
Solve the following problems in the space provided. Use the back of the page if needed. You must show your work in a logical fashion starting with the correctly applied physical principles. Your score will be maximized if your work is easy to follow because partial credit will be awarded: at the right is a graph of the velocity of a toy car as a function of time. Draw the graphs of position versus time and acceleration versus time. For full credit you need to explain your reasoning. The definition of acceleration, n o i t i s o p. 20 m a dv dt , means that the slope of the velocity time graph is the acceleration. So, the slope has three different constant values and is graphed at the right. The definition of velocity, v dx dt can be rewritten as, dx = vdt .
