RED AND BLUE
Wait for the applet to completely load. Click "(re)start". Time is given in seconds and position in metres.

Solve these problems algebraically, i.e. find and use the formulae for the motions.

Where (position) is the red ball at t = -5?    
Where (position) is the blue ball at t = -5?    
1. Where (position) and when (time) is the blue ball ahead of the red ball?
   
2. When (time) is the distance between the balls 30 m?
3. Draw Position vs. Time graphs for the two cars to illustrate the situation and the solutions. Describe the motion of the two balls in relation to each other over the interval -10 < t < 20.
