Work Done?
If someone has the time and patience could you help me in setting this problem up?
300kg object moves 4.5 meters down a 25 degree incline at a constant speed. It is kept from accelerating by a force pushing back on it. The effective coefficient of friction is .39
I need to:
a) calculate the net work done on the object
b) calculate the work done by the force pushing back on it
c) calculate the work done by gravity on the object.
I do not know where to begin. could someone point me in the right direction.
thanks,
dz
