i added a picture of the problem!
when the body is at point A the spring
is in relaxed status.
it lengths in relaxed statues is 0.6m
then a power P =20N is pulling the body to point B AB=0.25m
i was asked what is his speed when it reaches point B
so i made an equation that the total work equals the energy in the end
minus 0 (because there were no energy at the start)
i got that the speed of the body is square root of 15
v=3.87m/sec
the power P stops working a point B permemantly.
now i am being asked
what is the minimal distance that that body will get to the wall?
i tried to do the equation the bodies kinetic enrgy equals to its spring potential energy
it doesnt work i get that the amplitude is longer than 0.6m (not possible)
plz help
