The answer is 0.025J.
W=1/2*k*x^2
W=1/2*20*0.050^2
W=0.025J
B. By vibrations in wires or strings

Answer: 
Explanation:
Given
Time period 
Orbital speed 
mass of GS 
Radius of Mars 
Consider the mass of mars is M
Here, Gravitational pull will provide the centripetal force


Answer:

Explanation:
Since we are given time, acceleration, and final velocity, we can use the following formula to find the initial velocity:

Our given values:

<em>Acceleration is negative because the car is slowing down.</em>
Add the values to the formula, and solve for
:
