Answer: 10 m/s
Explanation: Velocity/Time
50/5= 10
:)
Answer:
From the formula of force:

since AB and k are constants:

x is a constant of proportionality
• when force is 4N, separation distance is 1

therefore, equation becomes

when r is doubled, r becomes 2. find F:

Answer:
potential energy is a type of energy an object has because of it's position
Answer:
The work done is "2000 J".
Explanation:
The given values are:
Force,
F = 200 N
Mass,
m = 55 kg
Displacement,
d = 10 m
Now,
The work done will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Jill is the input, as she creates the force. The wrench is the output because it gives the force to the finish peace of the chain.
