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 tracking radar lies in the vertical plane of the path of a rocket which is coasting in unpowered flight above the atmosphere. For the instant when θ = 30°, the tracking data give r = 25x104 ft, vr = 4000 ft/sec, and ω = 0.80 deg/sec. The acceleration of the rocket is due only to gravitational attraction and for its particular altitude is 31.4 ft/sec2 vertically down. For these conditions determine the velocity of the rocket v, the acceleration of r ar and angular acceleration α.
