Which of the following describe nonequilibrium conditions in the context applying Newton’s laws of motion?
A spacecraft decelerating upon reentry into the atmosphere.
A car accelerating through a traffic light.
A ball falling off the roof of a house.
A roller coaster going over the crest of a hill.
All of the above.
___________________________________________
You are in a car that is traveling at constant speed on a straight and level road before it suddenly starts down a hill. What can be said of your apparent weight relative to your true weight just as the car starts down the hill?
Your apparent weight is greater than your true weight.
Your apparent weight is less than your true weight.
Your apparent weight is equal to your true weight.
Help please!!!!!
A spacecraft decelerating upon reentry into the atmosphere.
Explanation / Answer
(e) all the above options are correct. All the statements follows non equilibrium state. Equilibrium state reach when central force of system is zero.
(b) when the car suddenly starts down a hill. In this condition your apparent weight will be slighter lower than the actual true weight.
