One end of a horizontal spring with force constant
76.0 N/m
is attached to a vertical post. A
4.00-kg
can of beans is
attached to the other end. The spring is initially neither stretched
nor compressed. A constant horizontal force of
56.0 N
is then applied
to the can, in the direction away from the post.
What is
the speed of the can when the spring is stretched 0.400 m?
At the instant the spring is stretched 0.400 m, what is the magnitude of the acceleration of the block?
