Above you looked at one particle leaving the grinder at a particular angle, but in practice the thousands of particles are leaving the grinder at all possible angles. If you are OCD about getting the fiery particles on your clothes, how far to the right from the center of wheel must you stand so that no particles will fall on you? QP: This is a hard problem. Now the thing is travelling on a circle of radius 2m counterclockwise, in such a way that acceleration vector of the particle is always at an angle of 45 with the velocity vector. If the particle started with an initial angular velocity of 1rad/s. Find the angular velocity as a function of time? Extra credit: What is the angle of the particle as a function of time, assuming at t=0 the particle was at angle=0?

Solution

Its spinning with RPM=1000.... I found d=2.435 leaving with a 60deg angle..
