A samll mass is hanging from an air track system with a mass of 10 grams. It is connected to a glider with a mass of 120 grams. The air track makes on angle of .35 degrees with the horizontal. Assume that the hanging mass and the glider are initially at rest.(adsbygoogle = window.adsbygoogle || []).push({});

a) if the mass drops a distance of 60 cm how much potential energy does it lose?

b)how far does the glider rise vertically when the small mass drops 60 cm

c) What is the increase in potential energy of the glider when it rise the given distance in the the previous problem

d)what is the total change in the potential energy of the two?

e)ignoring frictional losses what would be the final speed of the glider?

2. Relevant equations

no idea, what to use for this problem I would think I use the conservation of mrchanical energy equation.

3. The attempt at a solution

I have no idea how to even start please help!!! This is a pre lab and I need to undestand this stuff so I can do well with the lab its self

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
