PRACTICE IT
Use the worked example above to help you solve this problem. A
0.440 kg object attached to a spring of force constant 1.25
102 N/m is free to move on a
frictionless horizontal surface. If the object is released from
rest at x = 0.100 m, find the force on it and its
acceleration at x = 0.100 m, x = 0.0500 m,
x = 0 m, x = −0.0500 m, and x = −0.100
m.
| Position (m) | Force (N) | Acceleration (m/s2) |
|---|---|---|
| 0.100 | ||
| 0.050 | ||
| 0 | ||
| −0.050 | ||
| −0.100 | ||
