Problem
A 1.5kg block is released from rest at the top of a 2.0m long rough incline that makes an angle of 25∘ with the horizontal. The coefficient of kinetic friction on the incline is 0.15. After reaching the bottom, the block slides 0.40m across a rough horizontal surface (coefficient of kinetic friction 0.10) before compressing an ideal horizontal spring of force constant 400N/m. The block comes momentarily to rest after compressing the spring. What is the maximum compression of the spring?
(a) 0.14m
(b) 0.34m
(c) 0.19m
(d) 0.24m
