In the figure, we must apply a force of magnitude 80.0 N to hold the block stationary at x=-3.0 cm. From that position, we then slowly move the block so that our force does +4.0 J of work on the spring–block system; the block is then again stationary. What are the block's positions, in cm? ((a) positive and (b) negative)
Homework Answers
Work done = force * distance
So distance = work done / force
= 4 / 80
= 0.05 m so 5 cm
Then: -3 + 5 = 2 so the position is X= +2 cm
so it is positive

A spring and block are in the arrangement of the figure. When the block is pulled out to x = +5.0 cm, we must apply a force of magnitude 370 N to hold it there. We pull the block to x = 12.0 cm and then release it. How much work does the spring do on the block when the block moves from xi = +5.0 cm to (a) x = +4.0 cm, (b) x = -4.0 cm, (c) x=...

In the arrangement of the first figure, we gradually pull the
block from x = 0 to x=+3.0 cm, where it is
stationary. The second figure gives the work that our force does on
the block. The scale of the figure's vertical axis is set by
Ws = 3.0 J. We then pull the block out to
x=+6.0 cm and release it from rest. How much work does the
spring do on the block when the block moves from
xi=+6.0...

The block in the figure lies on a horizontal frictionless surface, and the spring constant is 50 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 3.0 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops. When that stopping...
A block of mass 1.8 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below
A block of mass 1.8 kg is attached to a horizontal spring that has a force constant 900 N/m as shown in the figure below. The spring is compressed 2.0 cm and is then released from rest. (a) A constant friction force of 3.4 N retards the block's motion from the moment it is released. How much is the spring compressed when the speed of the block is a maximum. (b) What is the maximum speed?
