4a. If a team pulls with a combined force of 9,000 N on an airplane with a mass of
30,000 kg, What is the acceleration of the airplane?

a=0.3m/s^2

Explanation:

Newton's 2nd law:

F=m*a

9000N=30000kg*a

9000N/30000kg = 30000kg*a/30000kg

0.3=a

so a=0.3m/s^2

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
