Horizontal Projectile Motion Calculator
To calculate the horizontal distance in projectile motion, follow the given steps: Multiply the vertical height h by 2 and divide by acceleration due to gravity g.. Take the square root of the result from step 1 and multiply it with the initial velocity of projection V to get the horizontal distance.. You can also multiply the initial velocity V with the time …
A global horizontal shear velocity model of the upper …
Sensitivity and resolution tests show that the horizontal resolution of the model is on the order of 800–1000 km to transition zone depths. The high wave-speed roots beneath the oldest parts of the continents appear to extend deeper for β h (z) than for β v (z) as in previous β h (z) models, but the resolution tests indicate that at least ...
