This is just a remix of @mgbk's project, with some alterations. I have explained the changes with comments inside.
Original instructions: Cat will jump when the truck reaches the horizontal position of the arrow by the road. Click on the green flag, then move the road arrow to where you want it. To make the cat leap instead of just dropping, set its speed (ft/s) and angle of leap from the horizontal with the sliders (the cat arrow shows the direction of the leap), then click somewhere else. To change the truck speed (ft/s), move the slider (95 ft/s corresponds to 65 mph), then click outside the slider. Press the space bar to start the animation. Positions are in feet.
