Question

As shown in the figure below, a stick of length L = 0.465 m and mass m = 0.260 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 θ = 30°.

Determine the following.

(a) magnitude of the force exerted on the stick by the bowling ball

(b) horizontal component of the force exerted on the stick by the floor

(c) vertical component of the force exerted on the stick by the floor
