CHAPTER 1. MOTION ALONG A STRAIGHT LINE 1. The following functions give the position as a function of time: i) x = A ii) x = Bt iii) x = Ct2 iv) x = Dcos !t v) x = E sin !t where A;B;C;D;E; ! are constants. A) What are the units for A;B;C;D;E; !? B) Write down the velocity and acceleration equations as a function of time. Indicate for what functions the acceleration is constant. C) Sketch graphs of x; v; a as a function of time. SOLUTION A) X is always in m. Thus we must have A in ...
