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?

the final momentum is equal to the input impulses..
Input: 10*2+20*2+30*2
output: 1/2 m v^2
