upon landing, a rightward-moving airplane accelerates from 72m/s to 8m/s in 5.3 s. Determine the magnitude kf the average acceleration of the airplane in m/s/s. Enter a numerical answer, accurate to the hundredths place

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
