Answer:
Explanation:
Conservation of momentum during the collision
0.023(230) + 2.0(0.0) = 0.023(170) + 2.0v
v = 0.69 m/s
The initial block kinetic energy will be converted to friction work
½mv² = Fd = μmgd
½(2.0)(0.69²) = 0.15(2.0)(9.8)d
d = 0.1619387... m
d = 16 cm
Answer: When two air masses collide at a front, one air mass may be pushed upward by the other. This is because one air mass is denser than the other.
Explanation: To know the correct answer, we need to know more about the Collision of Air masses.
<h3>What is an air mass?</h3>
- An air mass can be defined as the large volume of air in the atmosphere.
- It forms due to the uniform levels of temperature, humidity and pressure.
<h3>
What happens when two air masses collide with each other?</h3>
- When two air masses collide at a front, they never mix together.
- But they push against each other in such a way that, one will push upwards and the other will pushed downward.
- It happens because, one among the two air masses will be denser than the other.
- When a warm air mass meets a cold air mass, then the warm air will raise because it is lighter than the cold one.
Thus, from the above explanation, we can conclude that, one air mass may be pushed upward by the other, because one air mass is denser than the other when they came in contact with each other.

The answer for APEX Learning is Ocean
Two trucks have the same velocity but different mass. The truck with the ... factor that affects kinetic energy but not gravitational potential energy.
Answer:
If you pour water on the sand, the water seems to disappear into the sand. ... This happens because under pressure the sand grains actually push each other slightly farther apart, which makes more space between them. This means there is more space for water to flow into, resulting in a dry footprint on the beach.
