The rotors of a 15600-kg heavy-lift helicopter exert a downward force of 324000 n in order to accelerate itself and its external cargo upward at .5m/s^2. by itself, what upward force does the external cargo exert on the earth?

155,391.845 N upwards to earth

Explanation:

Given

mass of rotor=15600 kg

Downward force exert by helicopter =324000 N

therefore air exerts and upward force of 324000 N

acceleration of system

let m be the mass of cargo

therefore net downward force on helicopter is

Net force on helicopter

m=15,856.31 kg

Earth exerts a force of

Therefore cargo exerts a force of 155,391.845 N upwards to earth

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

another example of kinetic energy would be,

kinetic energy   >     moving energy
