solution:
the spring force exerted by spring with spring constant k is given by
where k is spring constant
and x is deformation of spring
in order to calculate word done by the spring
the work done by the spring as it is compressed from x=0 to x=L
inserting the limits x=0 and x=L
we get work done in terms of k and L
Answer:
r = √ x² + y² and θ = tan⁻¹ y / x
Explanation:
The polar coordinates are obtained by transforming the Cartesian coordinates (x y) into others (r tés), for this we use to find r the Pythagorean theorem
r = √ x² + y²
To find teas we use trigonometries
tan θ = y / x
θ = tan⁻¹ y / x
In general the angle can be given in any unit, but the most used in physics is in radians
