a free body diagrm for both masses, label all forces.
the +x-hat axis is up the incline, write an equation that shows
the sum of all forces in the x direction, for example SFx
and the sum of all forces in the y direction, SFy
Do the same thing for M2, assume that y-hat
at the equation you derived for question #2 above. How many forces
are you assuming in the x direction? How many in the y direction?
Can we ignore any of these forces? If so, which ones and why.
is the acceleration of the system? What would it mean if your acceleration
is the tension of the rope?
us assume that the ramp is 10 meters long (and that the crate slides
the entire 10 meters). What is the speed of the crate when it gets
to the top of the ramp?
our enterprising physics student stops the crate in 1.5 seconds,
then how much force does she apply to the crate?
