Field testing has revealed the following information: 1) The tank moves from rest to a speed of 70 km/hr in 10 seconds. 2) Using the breaking system, the tank is brought to a complete stop from a speed of 70 km/hr in 5 seconds. You are required to address all the questions below providing all calculations, graphs, and explanations as appropriate to back your answers. First: Motion of the tank: a) Find the average driving acceleration of the tank. b) Calculate the average breaking acceleration of the tank. c) For parts (a) and b above parts report your answers in US Customary Units (mile/hr) so that the information could be shared with experts from the US.

At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till it was eliminated and c) the average velocity of the fly? how can i find this pleaseHigh-speed motion pictures (3500 frames/second) of a jumping 230 μg flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure ( Figure 1).
