Problem 3) A 1-kg particle is pushed along a vertical smooth cardioid surface by a rod, as shown in Figure 2. The path of the particle can be described by the radial coordinate r = (1 + cos 0) m. The rod moves at a constat angular velocity of ė = 1 rad/sec. What is the magnitude of the force from the rod on the ball and what is the magnitude of the normal force from the curved guide on the ball at the instant that 0 = — rad. 6 rod Cardioid surface ģ Ꮎ r(0) = (1+ cos 0) m Figure 2: Particle pushed along cardioid surface by rod.
