If it requires 6.0 J of work to stretch a particular spring by 0.02 m from it's equilibrium length, how much more work will be required to stretch it an additional 0.04 m?

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
