Answer: The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.
Explanation:
A single pulley changes the direction of the effort, but it has
no mechanical advantage. The output force is the same as
the input force, so we'd say that the mechanical advantage is 1.
If there are two pulleys, with the rope going up and down and
around between them several times on its way from the effort
to the load, an arrangement that I think is called 'block and tackle',
then the mechanical advantage turns out to be the number of
strands of rope that are supporting the load.

Explanation:
Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.
Answer:
The speed of the piñata immediately after being cracked by the stick is .
Explanation:
Using the conservation of linear momentum:
(1)
Here:
m(s) is the mass of the stick
m(p) is the mass of the piñata
v(is) is the initial velocity of the stick
v(fp) is the final velocity of the piñata
So, we just need to solve the equation (1) to v(fp).
I hope it helps you!
