A 5kg object starts at rest and has a force applied to it of 10 Newtons for 2 seconds, followed by 20 Newtons for 2 seconds, followed by 30 newtons for 2 seconds, all in the same direction.

Question

A 5kg object starts at rest and has a force applied to it of 10 Newtons for 2 seconds, followed by 20 Newtons for 2 seconds, followed by 30 newtons for 2 seconds, all in the same direction. 
a. Determine its final velocity

b. Sketch a graph of force vs time

c. Create a different force scenario that will result in the same final velocity and sketch a force vs time graph for it.

d. What do the graphs have in common?
