Homework Statement
Experiment set up.
A 208g weight is attached via a pulley system to a block on an inclined plane. What is the work done by the suspended mass as the car is lowering at a constant velocity? And work done by gravity?
Distance weight moves down - 24.7cm
Incline is 30 degrees
Homework Equations
[itex]F=ma[/itex]
[itex]w=Fdcos(\theta)[/itex]
The Attempt at a Solution
So, in this case, work would be negative, right? Because the direction of the force from the suspended mass is going UP the incline, and the direction of moment is DOWN the incline?
The block is 474g
I'm not sure where to start. If I use the basic work formula and do
[itex]\(-208*980)*24.7[/itex]?
