The 4 model rockets just have their engine turned off when they are at the same height. All the rockets are aimed straight up, but their speeds differ. Although they are the same size and shape, the rockets carry different loads, so their masses differ. The specific mass and speed for each rocket are given below: A. speed = 30m/s, mass = 700g B. speed = 40m/s, mass = 500g C. speed = 20m/s, mass = 600g D. speed = 20m/s, mass = 500g How much maximum height each model rocket will reach? Why they will reach different heights?
d. Force is a vector quantity and thus has both a magnitude and a direction. A vector can be represented graphically by a line drawn to scale in the direction of the line of action of the force. To distinguish between vector and scalar quantities, various ways are used. Identify and explain threeof these ways.
