Question
A 2.40 kg block on a horizontal floor is attached to a
horizontal spring that is initially compressed
0.0400 m. The spring has force constant 840 N/m.
The coefficient of kinetic friction between the floor and
the block is 0.390. The block and spring are released
from rest and the block slides along the floor.
Part A
What is the speed of the block when it has moved a distance of 0.0130 m from its initial position? (At this point the spring is
compressed 0.0270 m.)
Express your answer with the appropriate units.
