A group of students conduct the Atwood?s Machine experiment the same way we did with a total mass of 300 grams. Here is their data:

Which planet are they on?

a. Earth (9.81 M/s ² )

b. Mercury (3.8 M/s ² )

c. Mars (3.7 M/s ² )

d. Venus (8.87 M/s ² )

e. Neptune (8.69 M/s ² )

f. Other

What is the uncertainty in the g value if the uncertainty in the total mass is 2 grams?

You have to use the techniques of error propagation.

Estimate the magnitude of the total constant resistive forces. Answer in mN(millinewtons). 281.5100

If the uncertainty of the total mass is 2 grams, what is the relative uncertainty of the friction? Answer as a percentage without typing eh percent sign.
