Question

<p>&#916;x= x_final -x_initial</p>
<p>Choose the natural coordinate system of the dynamics track, origin at 0cm mark, positive to the right. Place the cart 30 cm mark on the track and then perform the following 4 consecutive displacements each occuring over some time interval:</p>
<p>a) move cart slowly to the 50cm mark</p>
<p>b) remin at 50cm for several seconds</p>
<p>c) move cart to 100 cm fast</p>
<p>d) move cart slowly back to 60 cm mark</p>
<p>Calculate the displacement over each seprate interval. Show the actual arithmetic in your calculations, that is, showt he subtractions you make to calculate displacements</p>

Explanation / Answer

displacement = final position - initial position A) 30 cm to 50 cm (50-30)= 20 cm B) remain at 50 cm (50-50) so no displacement C) 50 cm to 100 cm (100-50) = 50 cm D) 100 cm to 60 cm (60-100) = -40 cm
