Calculate the force exerted on a rocket when the propelling gases are being expelled at a rate of 1400 kg/s with a speed of 3.6×104 m/s .

Based from Newton's second law of motion, the net force exerted on an object is equal to the product of its mass and the acceleration. 
 
       F = m x a 

From this item, we are given of the expulsion rate and the speed, which may also be multiplied with each other in order to determine the net force.

     F = (1400 kg/s)(3.6 x 10^4 m/s)

Simplifying,
    F = 50400000 N

In scientific notation,

  F  = 5.04 x 10^7 N 

the simple machine has three main features. they are:

loadfulcrumeffort

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

Depending on how the continental plates move it can cause a continental scale shift.
