Answer:
Explanation:
Given
Beta rocket has twice the mass of Alpha engine
suppose alpha has a mass of m so beta has 2 m mass
Thrust force on alpha is F
thrust force on beta is 2 F
Acceleration of alpha 
Acceleration of beat 
Therefore acceleration of alpha and beta is same
I believe that the correct answer you are looking for is the distance traveled
Answer:
The work done to lift the counterweight equals the potential energy acquired
Explanation:
since this is vertically applied force on the counterweight, and the distance the force is displacing the counterweight is in the same direction as the applied force, it equals the gained potential energy
Probably false. but correct me if i’m wrong
