Model Rockets Moving Upward Net Force Worksheet-GC .

Name Model Rockets Moving Upward-Net Force 21 The eight figures below depict eight model rockets that have just had their engines turned off. All of the rockets are aimed straight up, but their speeds differ. All of the rockets are the same size and shape, but they carry different loads, so their masses differ. The specific mass and speed for each rocket is given in each figure. (In this situation, we are going to ignore any effect air resistance may have on the rockets.) At the instant when the engines are turned off, the rockets are all at the same height. Rank these model rockets, from greatest to least, on the basis of the net force on them after the engines have turned off.
