Calculate the acceleration of a 300000-kg jumbo jet just before takeoff when the thrust of it's four engine is 30000n?

Answer 1

Easy; use the acceleration formula: A=F/M. Now, there are four engines, correct? So you multiple the 30,000 by 4. This gives you 120,000. Divided that by the original 300,000. Your answer should be .4 m/s squared.
