The ground does 1600T of work to stop a falling ball in .05 M. What force is needed?

Work is defined as a displacement of an object or thing due to being acted upon by a force. The more work done, the more force is used when compared to the distance the force was done over. We can find the amount of force (measured in joules) using the equation:


`W=F/d`


Work is equal to the force applied divided by the distance. In your question, the work done to the ball is equal to...

Work is defined as a displacement of an object or thing due to being acted upon by a force. The more work done, the more force is used when compared to the distance the force was done over. We can find the amount of force (measured in joules) using the equation:


`W=F/d`


Work is equal to the force applied divided by the distance. In your question, the work done to the ball is equal to 1600J (I assume you meant J and not T as T is not a unit of force). The distance here would be equal to 0.05 meters. Since we're trying to find the force done, we need to re-arrange our problem by isolating the force variable. Then we plug in our variables and find our answer.


`W=F/d`


`Wd=F`


`(1600J)(0.05m)=F`


`F=80N`


In order for the ball to stop in the given distance with the given amount of work it would have to have 80 Newtons (SI unit for force) placed upon it to bring it to a stop by the ground. I hope that helped you better understand the work equation!

How can a 0.5 molal solution be less concentrated than a 0.5 molar solution?

The answer lies in the units being used. "Molar" refers to molarity, a unit of measurement that describes how many moles of a solu...
