What is the magnitude of the upward thrust force (assumed constant)?Express your answer with the appropriate units

Complete Question

A helicopter of mass   kg is descending vertically at 3.00 m/s. The pilot increases the upward thrust provided by the main rotor so that the vertical speed decreases to 0.450 m/s as the helicopter descends 5.00 m. What is the magnitude of the upward thrust force (assumed constant)?Express your answer with the appropriate units.

The value is  

Explanation:

From the question we are told that

   The mass of the helicopter is  

   The initial descending speed is

   The  descending speed after the upward thrust has been increased is

    The  height when descending speed is  is  

Generally according to the kinematics equations

Here a is the acceleration due to gravity plus the acceleration of the helicopter

So

    a  =  

the negative sign is due to the fact that the direction of the plane is in the negative y axis

So

=>    

=>      

=>      

Generally the thrust force is mathematically represented as

=>

=>

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
