A 3.00-kg mass starts from rest and slides a distanced down a frictionless 30 degree incline. Whilesliding, it comes into contact with an unstressed spring ofnegligble mass, as shown below. (drawn best i could) The massslides an additional .200m as it is brought momentarily to rest bycompression of the spring (k = 400N/m). Find the initial separationd between the mass and the spring.

**Answer** d = .344m

 

"spring" e = 30
