2. Write out the final answer for the coefficient of friction as the average of the values in the
table (average all of your coefficients of frictions, and write that average below)
The average is = 0.2559975 or 0.256
3. Using similar methods as in questions #1 and #2, estimate the mass of the object in the
present, the mystery mass. Include a description of the process and the mathematics
of estimating the mass. Use the average coefficient of friction written in #2 to solve for
the mystery mass.
IE
4. Set an object (anyone you choose) to be moving at a constant speed. Describe the
procedure for keeping the object moving at a constant speed. Write down the speed
which the object is moving, as well.

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels.the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause,directly and indirectly, for such a rise in sea level is

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
