Since the orange rolls off the table and is (falling) its potential energy turnes into kinetic energy.
Hope this helped

Answer:
2.5 m/s
Explanation:
The velocity of the package relative to the ground = the velocity of the package relative to the helicopter + the velocity of the helicopter relative to the ground
v = 0 m/s + 2.5 m/s
v = 2.5 m/s
At the moment it is released, the package is rising at 2.5 m/s.
Answer:
Time period, T = 1.98 seconds
Explanation:
It is given that,
Mass of the block, m = 300 g = 0.3 kg
Force constant of the spring, k = 3 N/m
Displacement in the block, x = 3 cm
Let T is the period of the motion of the block. The time period of the block is given by :
T = 1.98 seconds
So, the period of the motion of the block is 1.98 seconds. Hence, this is the required solution.
1.44Ns
6.3m/s
Explanation:
Given parameters:
Mass of object = 230g = 0.23g
height of fall = 2m
Unknown:
Impulse = ?
velocity on impact = ?
Solution:
We are going to apply one of the equations of motions to solve this problem.
The most appropriate one is:
V² = U² + 2gH
where V is the final velocity
U is the initial velocity
g is acceleration due to gravity as the body falls with aid of gravity = 9.8m/s²
H is the height of fall
since the body was initially at rest, U = O
V² = 2gH
V = √2 x 9.8 x 2 = 6.3m/s
Impulse = mass x velocity = 0.23 x 6.3 = 1.44Ns

A). Earth completes one rotation on its rotation axis
every (3 minutes and 56 seconds less than 24 hours).
This causes night and day. It's rotation, not precession.
B). Earth completes one orbital revolution around the sun
every (365 plus a little bit) days. It's revolution, not precession.
C). I'm not sure what happens on a cycle of 512 years.
It may have something to do with the moon. But whatever
it is, it's not precession.
D). When you spin a top and it starts to run down, the first
thing that happens is that the handle of the top, or the point
on top of the top, starts moving in a circle. That's precession.
That's what the Earth's axis is doing. The north pole points
toward the north star (Polaris) now. But the north pole is
actually drawing out a big circle in the sky, and other stars
will become the "north star" far in the future.
The north pole draws out a full circle in the sky, roughly
once every 26,000 years. That's precession.
