A plane comes in for landing at a velocity of 80 meters per second west . As it touches down, it decelerates at a constant rate of 3 meters per second per second. What is the minimum length of runway needed for this plane to come to a complete stop ( on the runway)? A.) 240m. B.)682m C.) 859m. D.) 1067m
C is the answer, you have to add up every single number, so first you would add 80 then add 77 then 74 etc. decrease it by 3 then add it to your total until there is nothing left to add then compare that to the runway sizes.
