If the mass of a plane is 2,500 kg and the net force on it is 14,000 N, what is the plane's acceleration?

• physical science -

a=F/m = 14000/2500 =5.6 m/s^2

• physical science -

A force is used to raise a 50 kg crate through a height of 4m at a constant speed.how much gravitati

• 12th grade math -

* newton's second law:
a=F/m
=4000N/2500kg
=5.6m/s^2 (in the direction of a force)
