### Find the mass of the box

Assignment Help Physics
##### Reference no: EM13315068

while unloading furniture, a worker slides a heavy box down the ramp on the rope. The ramp is inclined 60 degree to the horizontal and the worker applies upward forces of 450 N parallel tot the ramp to move the box without accerelation. If the coefficient of kinetic friction between the ramp and the box is 0.25, find the mass of the box.
