WebAverell Chen. The horizontal distance travelled by a projectile is called its range. A projectile launched on level ground with an initial speed v0 at an angle θ above the horizontal will have the same range as a projectile launched with an initial speed v0 at 90° − θ and maximum range when θ = 45°. WebSolve for the magnitude and direction of the displacement and velocity using s = √x2 + y2, Φ = tan−1(y/x), v = √v2x + v2y, where Φ is the direction of the displacement →s. Figure 4.12 (a) We analyze two-dimensional projectile motion by breaking it into two independent one-dimensional motions along the vertical and horizontal axes.
WebPeak ground velocity (PGV) has many applications in engineering seismology and earthquake engineering. New-mark et al. (1973) used PGV, together with peak ground … WebGround-borne vibration. Peak particle velocity (PPV) can be calculated using the following formula proposed by the United States Bureau of Mines (USBM): V = k ( D / √Q) -e. Where: V = peak particle velocity (mm/s) D = distance from blast to measurement point (m) Q = charge per delay (kg) Note: D/√Q is the scaled distance term (m/√kg) Note ...

Earthquake energy is dispersed in waves from the hypocentre, causing ground movement omnidirectionally but typically modelled horizontally (in two directions) and vertically. PGA records the acceleration (rate of change of speed) of these movements, while peak ground velocity is the greatest speed (rate of movement) reached by the ground, and peak displacement is the distance moved. These values vary in different earthquakes, and in differing sites within one eart…
