A spring of elastic constant 17 N/m is compressed a distance of 45 cm. Calculate the amount of work that it is capable of doing. Please Help

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

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
