The choice of a seating material for moving vehicles depends upon its ability to resist shock and vibration. From the data shown in the graphs, determine the impulses created by a falling weight onto a sample of urethane foam and CONFOR foam. Units Used: ms = { 10 }^{ -3 } s Given: { F }_{ 1 } = 0.3 N , { t }_{ 1 } = 2 ms , { F }_{ 2 } = 0.4 N , { t }_{ 2 } = 4 ms , { F }_{ 3 } = 0.5 N , { t }_{ 3 } = 7 ms , { F }_{ 4 } = 0.8 N , { t }_{ 4 } = 10 ms , { F }_{ 5 } = 1.2 N , { t }_{ 5 } = 14 ms
