The acceleration a of an object is directly proportional to the net force acting on it and inversely proportional to its mass. That doesn't help me too much... Maybe I'm not putting two and two together. Is the answer "E" then?

Homework Statement A moderate force will break an egg. However, an egg dropped on the road or sidewalk usually breaks, while one dropped on the grass usually does not break. This difference is because for the egg dropped on the grass: A. the change in momentum is greater B. the change in...

Thank you.

It's really not a quick question... I am really just unsure of myself... I take that from your comment you are trying to tell me that the answer then is "E"? Please confirm if the answer is E then. Thank you.

Homework Statement 13. As a car skids with its wheels locked trying to stop on a road covered with ice and snow, the force of friction between the icy road and the tires will usually be: (Please note that “normal” and “perpendicular” have the same meaning) A. greater than the normal...

ok, well how would I do that? the possible answers to the question are a. 100, b. 83, c. 74, d. 19. That is where I am stuck.

Homework Statement By what factor is the total pressure greater at a depth of 850 m of sea water than at the surface where the pressure is one atmosphere? (water density = 1000 kg/m3, one atmosphere pressure = 1.01 x 105 Pascals (N/m2), g = 9.8 m/s2 ) Homework Equations P=P(initial)+ρgh...
