Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

A bullet of mass m=0.1 kg is fired with a velocity v0=500 m/s forming an angle θ=30° with the horizontal and gets lodged in a wooden block of mass M=10 kg. The block can roll without friction on a hard floor and is prevented by springs from hitting the wall. Calculate theamplitude and period of vibration of the block and embedded projectile. Each one of the three springs has a stiffness k=3 kN∕m.
