Answer:
-0,2 m/s²
Explanation:
Acceleration = α = (V-V₀)/t
α = (10-14)/20 = -0,2 m/s²
Answer:
We must duplicate the length of the rope (R'=2R) to get
Explanation:
The equation of the centripetal force is given by:
Where:
R is the length of the rope
m is the mass of the object
v is the speed of the object
If we want to reduce the centripetal force in half, we can duplicate the length of the rope (R'=2R), which means:
I hope it helps you!
Answer:
Your answer would be B. fall
Explanation:
This is because sliding would be continuous it just said a fragment of rock fell vertically. Hope this helps

Without friction, the amount of work only depends on the final height,
and is not affected by the route used to get there.
If the ramp has no friction, then it has no effect on the total amount
of work done. The work to lift the load straight up is the same.
If the ramp has some friction, then it takes more work to use the ramp
than to lift the load straight up. Then the work to lift the load straight up
would be less than when the ramp is used.
