a normal egg of mass 60.0 g has a shell of mass 2.00 g. suppose a super-egg of mass 300.0 g is developed, which is found to have a shell of mass 7.60 g. what is the ratio of the shell thickness of the super egg relative to the thickness of the shell of the normal egg? assume that both eggs have a similar shape.

How much force must a locomotive exert on a 12840-kg boxcar to make it accelerate forward at 0.490 m/s2?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?
