Answer: v = 0.6 m/s
Explanation: <u>Momentum</u> <u>Conservation</u> <u>Principle</u> states that for a collision between two objects in an isolated system, the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.
Momentum is calculated as Q = m.v
For the piñata problem:
Before the collision, the piñata is not moving, so .
After the collision, the stick stops, so .
Rearraging, we have:
Substituting:
0.6
Immediately after being cracked by the stick, the piñata has a swing speed of 0.6 m/s.
I think it's 16.8 because you multiply 5.6x3=16.8
Well, in my own personal case, I can actually move the air in either
direction through both of those.
When I move the air inward from the outside, it's warmed and moistened.
When I move it outward from the inside, it's not.
Answer:
0.96 m, upward
Explanation:
Initial velocity, u=0
Where
Substitute the values
Hence,the block moves upward because displacement is positive.
<span>Well iron, nickle, and cobalt can be natural magnets because they have minerals or metals that generate a stable magnetic field without artificial inducement. A piece of wood cannot be a natural magnet because it does not have metals or minerals that allow it to generate a stable magnetic field. Other types of metals that are magnetic are man made.</span>
