Question

As shown in the figure below, a stick of length - 0.395 m and mass m -0.275 kg is in contact with a rough floor at one end and a frictionless bowling ball (diameter d = 17.50 cm) at some other point such that the angle between the stick and the floor is 6 = 30º. Determine the following. 30.0" (a) magnitude of the force exerted on the stick by the bowling ball N (b) horizontal component of the force exerted on the stick by the floor N (c) vertical component of the force exerted on the stick by the floor N
