Which equation best describes the law of conservation of momentum?

2 answers:

8 0

The law of conservation of momentum states that for two objects colliding in an isolated system, the total momentum before and after the collision is equal. Momentum should be conserved. Hope this answers the question. Have a nice day.

Andrew kicks a ball along a straight path. The ball rolls straight forward for 13.2 meters. Then Andrew kicks the ball straight

tresset_1 [31]

Answer: 22.7 meters

Explanation: The distance traveled is how much the ball has rolled in total, this means the lenght of the path that it has followed from begining to end.

Since it first travels 13.2 meters and then 9.5 meters, if we sum this quantities:

13.2 + 9.5 = 22.7 meters

So 22.7 is the distance that the ball has traveled.

Define average velocity and instantaneous velocity when are they same

Vlada [557]

Answer:

Look to the explanation

Explanation:

Average velocity: is the average rate of change of displacement with

respect to time

Average velocity is a measure for distance traveled in a given time

We can calculate the average velocity by the rule $v=\frac{s}{t}$

where s is the displacement and t is the time

Instantaneous velocity: is the velocity of an object in motion at a

specific point (x , t)

instantaneous velocity is the limit of velocity as the change in time

approaches zero

We can calculate the instantaneous velocity by the rule $v=\frac{ds}{dt}$

Average velocity is equal to the instantaneous velocity when

acceleration is zero
