[See image]. Rank from largest to smallest, the momenta of the objects shown in the image.
2 > 1 = 3 = 5 > 4
Starting from rest, object 1 is subject to a 10 N force for 3.0 s. Object 2, which also starts from rest, is subject to a 20 N force for 2.0 s. Which object would have the greater final speed and why?
Object 1 - Although, object 2 has a larger change in momentum than object 1, its change in momentum is not double that of object 1, but its mass is twice that of object 1.
