We recently did a lab with an inclined board and a box connected to a hanger with mass (over a pulley).
I've gotten all of the calculations I need except for two. I was wondering if I could get a little help.
When θ = 30°, what was the k-work done on the box by the suspended weight when the box moved (a) up the incline and (b) down the incline?
When θ = 30°, what was the k-work done on the box by gravity when the car moved (a) up the incline and (b) down the incline?
(a) For the box going up the incline, what percentage of the k-work done by the suspended weight is lost to friction? (b) For the box going down the incline, what percentage of the k-work done by gravity is lost to friction?
Theta is the angle of inclination. The displacement would be 0.218m. The suspended mass was 0.190kg to allow the box to move up the incline. The mass was 0.053kg to allow the box to move down the incline.
Any help would be greatly appreciated.
