The slotted arm OB rotates in a horizontal plane about point O of the fixed circular cam

Question:

The slotted arm OB rotates in a horizontal plane about point O of the fixed circular cam with constant angular velocity θ˙ = 15 rad/s. The spring has a stiffness of 5 kN/m and is uncompressed when θ = 0. The smooth roller A has a mass of 0.5 kg. Determine the normal force N which the cam exerts on A and also the force R exerted on A by the sides of the slot when θ = 45°. All surfaces are smooth. Neglect the small diameter of the roller.
