You drop an egg onto i) the floor and ii) a thick piece of foam rubber. In both cases the egg does not bounce. Which combination of statements about the egg drop is correct? A. The impulse is greatest with the floor, and average force is the same in both cases B. The impulse is the same in both cases, and the average force is greatest with the floor C. The impulse and the average force is the same in both cases D. The impulse is the greatest with the foam rubber, and the average force is the same in both cases

Answer #1

Impulse is defined as the change in momentum.

Since in both cases the egg has same initial velocity(before impact) and final velocity (=0) so the impulse in same for both cases.

Egg comes to rest faster on floor compared to foam

Avg Force = Impulse / T

Since Tfloor < Tfoam , So Avg Forcefloor > Avg ForceFoam . Thats why egg tends to break off the floor and not on foam

So option B is correct.

Thanks, Please like if the solution was helpful.

5. How heavy are the backpacks carried by college students? To estimate the weight of backpacks carried by college students, a researcher weighs the backpacks from a random sample of 58 college students. The average backpack weight ends up being 15.7 pounds, with a standard deviation of 2.4 pounds. If you use this data to construct a 90% confidence interval, what will the margin of error be for this interval? Try not to do a lot of intermediate rounding until...

In this exercise, you will analyze the supply-demand equilibrium of a city under some special simplifying assumptions about land use. The assumptions are: (i) all dwellings must contain exactly 1,500 square feet of floor space, regardless of location, and (ii) apartment complexes must contain exactly 15,000 square feet of floor space per square block of land area. These land-use restrictions, which are imposed by a zoning authority, mean that dwelling sizes and building heights do not vary with distance to...
