A coin of mass m and rotates on a circular platform of radius r at the fastest speed possible without the coin sliding off. In this case, the coin makes each revolution in 4.5 seconds (its period). The coin and platform have a coefficient of friction,μ, that is unchanged. If the radius of the table is increased by a factor of 3 , what would be the new period? Give your answer to 1 decimal place.

Consider a disc of mass 0.44kg, with radius 0.5 m on a slope with angle 45 degrees to the horizontal. It has a good grip on the slope and does not slip. The disc is constructed so that its mass per unit area, ρ(r) = r1/2 kg m−2, with r being the radial distance in metres from the axis of the disc. What is the acceleration of the disc down the slope?
An object of mass M = 2.00 kg is attached to a spring with spring constant k = 22.0 N/m whose unstretched length is L = 0.110 m , and whose far end is fixed to a shaft that is rotating with an angular speed of ω = 1.00 radians/s . Neglect gravity and assume that the mass also rotates with an angular speed of 1.00 radians/s as shown. (Figure 1) When solving this problem use an inertial coordinate system, as drawn here. (Figure 2) Given the angular speed of ω = 1.00 radians/s , find the radius R(ω) at which the mass rotates without moving toward or away from the origin.
Consider the yo-yo (of mass M and outer radius R) shown in the figure, where the string is being pulled with a force of magnitude F (F < M g) at an angle θ to the horizontal. The radius of the inner axis is r (so that r < R). Assume that the angle ranges from 0 to π/2, and the coefficient of static friction with the ground is very large. 1)Enter an expression for the critical angle (in radians, between 0 and π / 2) at which the yo-yo will remain motionless. Use γ = r / R to simplify your expression.
