Answer:

Explanation:
Given that
At X=0 V=Vo
At X=X1 V=0
As we know that friction force is always try to oppose the motion of an object. It means that it provide acceleration in the negative direction.
We know that



So the friction force on the box
Ff= m x a

Where m is the mass of the box.
<span>Is it true that nighttime air temperatures on a cloudy night are lower than they would be on a clear night?</span>
object's weight is the independent of mass and gravity .
Weight = mass × gravity
It doesn't because when u threw it the first time, u notice that the ball eventually came to a stop because of the force that was acting upon it. Although when u throw it harder it will start out faster than the first time u threw it because u put more kinetic energy onto the ball. But the same thing happens with this ball that happened to the second ball, they both have a type of force acting upon them.
Answer;
-Flammability
Explanation;
-Chemical properties are characteristics of a material that become evident when the material undergoes a chemical reaction or chemical change. It is a substances ability to change into a whole new substance.
-Examples of Chemical Property include flammability, ability to rot, reactivity, ability to tarnish, ability to rust. Iron, for example, combines with oxygen in the presence of water to form rust.
