So if there were a coefficient of friction of say 0.1 in this problem, then the 99 blocks together would produce a friction force of 0.1 x 99M x g and the one block to the right would produce a friction force of 0.1 x M x g.
And each of these two friction forces would be the amount that is...
I think if the object that is acted upon is on the the X-Y plane, for example, then an applied force can't be considered a normal force if the former is in the same plane as the latter. In order for an applied force to be a normal force it has to be on the Z plane.
Is this right?

THE QUESTION IS THIS:
A skier of mass 55.0 kg slides down a slope 11.7 m long, inclined at an angle f to the horizontal. The magnitude of the kinetic friction is 41.5 N. The skier’s initial speed is 65.7 cm/s and the speed at the bottom of the slope is 7.19 m/s. Determine the angle f from...
