Final velocity of a block on a spring pulled downhill

[QUOTE="kuruman, post: 6826276, member: 192687"] I am having problems with the numbers, not necessarily with the post. The down-incline component of the weight is ##mg \sin20^o=335~##N. The maximum value of the driving force is 200 N. The two added together give a down-incline maximum force of 535 N. When the spring is stretched by 2 m, the up-incline force is ##kx=8000~##N which is much larger than the relatively pitiful down-incline force. This means that the spring will never be stretched by 2 m so what are we supposed to find? Something is amiss. [/QUOTE]
