A satellite in free space sweeps stationary interplanetary dust at a rate dM//dt=alphav where M is the mass and v is the velocity of the satellite and alpha is a constant. What is the deceleration of the satellite?

A satellite in free space sweeps stationary interplanetary dust at a r

1.	A satellite in free space sweeps stationary interplanetary dust at a rate dM//dt=alphav where M is the mass and v is the velocity of the satellite and alpha is a constant. What is the deceleration of the satellite?
Answer» `-alphav^(2)` `-(alphav^2)/(2M)` `-(alphav^2)/(M)` `-(2alphav^2)/(M)` SOLUTION :`F=((dM)/(DR))v=alphav^(2)(because(dM)/(dt)=alphav)` `therefore"RETARDATION"=-(F)/(M)=-(alphav^2)/(M)`
