Vertical velocity Definition and 47 Threads

The Flash: Vertical Velocity (formerly known as V2: Vertical Velocity) is a steel Inverted Impulse roller coaster located at Six Flags Discovery Kingdom in Vallejo, California. It is California's first and only Spiraling Impulse Coaster, built by Intamin and opened in 2001. It stands 150 ft tall (46 m) and reaches speeds of up to 70 mph (110 km/h). The ride is tied with Medusa and Superman: Ultimate Flight in the same park for tallest roller coaster in Northern California.

    An expression for the vertical velocity as a function of time

    A rocket of initial mass m0 is launched vertically upwards from the rest. The rocket burns fuel at the constant rate m', in such a way, that, after t seconds, the mass of the rocket is m0-m't. With a constant buoyancy T, the acceleration becomes equal to a=T/(m0-m't) -g. The atmospheric...

    Why Vertical Velocity changes & Horizontal does not?

    Projectile motion involves velocity in vertical and horizontal direction. It is important to understand that the two are independent of each other. Solving problems becomes much easier with this simple understanding.
