Task VI:
As a technical engineer in the army, you are part of a team in charge of testing and commissioning a new tank recently purchased by the artillery.
Field testing has revealed the following information:
The tank moves from rest to a speed of 70 ??/ℎ? in 10
Using the breaking system, the tank is brought to a complete stop from a speed of 70 ??/ℎ? in 5
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:
Find the average driving acceleration of the tank.
Calculate the average breaking acceleration of the tank.
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.
