1. An object is moving along the horizontal line, with the position as a function of time is given as [ x(t)=left{egin{array}{c} t^{2}, quad 0 s leq t leq 10 s \ -0.5 t^{2}+30 t-150, quad 10 s leq t leq 30 s end{array} ight. ] Determine: a. Total displacement! b. Total distance! c. Average velocity within the 30 s interval! d. Time interval when the object is speeding up and when the object slowing down! e. Time when the object is at rest!

An object moves so that its position changes in the following way: $x(t)=-100 m+(30 m/s) t+\left(3.0 m/s^{2}\right) t^{2}.$ (a) What kind of motion is this (constant velocity, constant acceleration, or changing acceleration)? (b) Describe all of the known quantities for this motion. (c) Invent a story for the motion. (d) Draw a velocity-versus-time graph, and use it to determine when the object stops. (e) Use equations to determine when and where it stops. Did you get the same answer using graphs and equations?

(1I) The position of a small object is given by $x=34+10 t-2 t^{3},$ where $t$ is in seconds and $x$ in meters. (a) Plot $x$ as a function of $t$ from $t=0$ to $t=3.0 \mathrm{s}$ (b) Find the average velocity of the object between 0 and 3.0 $\mathrm{s}$ (c) At what time between 0 and 3.0 $\mathrm{s}$ is the instantaneous velocity zero?
