The graph below shows the external force applied to a 15-kg object throughout a displacement of 8 m.

- How much work was done on the object throughout the 8-m displacement?

- If the object was initially moving at 4.0 m/s (before the force was applied), calculate the objects kinetic energy after the work was done on it.

- Calculate the speed of the object after the work was done on it.

- Next, the object hits a compressional spring with a spring constant of 650 N/m. Calculate the maximum compression of the spring.
