We know that,
v = rw
a = v^2/r = mg
mg = (rw)^2/r
r = mg/w^2
where, w = (5000rev/min)*(2πrad/rev)*(1min/60s)
= 5000*2*pi/60 = 523.6 rad/s
r = 3000 * 9.8/(523.6)^2
= 0.107 m

Hint: For this problem, all angle units must be converted to the 'natural' unit for angular displacement, and without a picture, you won't get far at all. A bike racer speeds up on a horizontal road. The wheel of radius 0.34 m is rotating at a rate of 0.70 revolutions per second at time = 0.0 s. The racer accelerates at a constant rate so that 0.22 seconds later her wheel rotates at 1.10 revolutions per second, after which she...

Consider a bug which is crawling on the surface of a turntable rotating with constant angular velocity wo. List all the forces acting on it in a system of coordinates painted on the turntable (z is perpendicular to the turntable and the rotation is around the z-axis) and the direction of each of those forces, in each of the following cases: a) when the bug is moving out from the center of the turntable along a radius at constant speed...
