A ball is attached to a cord of length L, which is tied to a frame attached to a truck bed as shown in figure (a), below. The ball-truck system is initially traveling to the right at constant speed vi, with the cord vertical. The truck suddenly stops when it undergoes an inelastic collision with a low wall as shown in figure (b), below. The suspended ball swings through an angle θ. a a (i) b (i) (a) Show that the original speed of the truck can be computed from vi = 2 gL(1−cos⁡(θ)). When the truck stops, the ball begins moving like a -- Select--- ∇. The truck's initial velocity can be derived using ---Select-- .

A uniform meter-stick of mass M = 10 kg is hanging with the support of a hinge A and a cable at an angle θ = 45∘ as shown in the figure below. If the block of mass m = 8 kg moves beyond x = 0.73 m from hinge A, the cable breaks. Find the maximum tension T the cable can withstand. [5 Pts]With the block placed at x = 0.5 m, what are the horizontal and vertical components of the force on the bar from hinge A ? [10 Pts] Suppose the block of mass m is now at x = 0.74 m and the cable breaks, what is the angular acceleration of the system right after the cable breaks (You can assume that the block is a point mass)?
