Particle moving in spiral where decreasing radius r is given by $$r=b-ct$$ and the angular velocity increases $$w=kt$$ . Where b,c,k are constants. What is the speed as a function of t? What is the speed when r=0? if tangential velocity is given by $$v=wr$$ would that mean the speed is $s(t)=|wr|=(kt)(b-ct)$
