Answer:
Transform Boundary
Explanation:
The just slide past each other
Answer:
Explanation:
First, we will use conservation of the linear momentum:
so:
where is the mass of the dart, is the speed of the dart just before it strickes the apple, the mass of the apple and the velocity of the apple and the dart after the collition.
Then, solving for V_s:
now, using the conservation of energy:
so:
where g is the gravity and h how high does the apple move upward.
Now, replacing and solving for h, we get:

Answer:
A derived unit is called so because it is the product of two more basic units. The basic unit of area is the cubic meter (m³) for volume. By derived unit, it refers to any given quantity which cannot be measured directly with any device. For eg., We can't measure density of a substance with a rule, or scale, or bucket.
