Question: noting that x is position, v is velocity, m is mass, and a is acceleration, which of the following expressions will have units of kg x m/s^2. select all that apply
RRT and Velocity Obstacles-based motion planning for Unmanned Aircraft Systems Traffic Man…
In this paper, an algorithm for Unmanned Aircraft Systems Traffic Management (UTM) for a finite number of unmanned aerial vehicles (UAVs) is proposed. This algorithm is developed by combining the Rapidly-Exploring Random Trees (RRT) and Velocity Obst...
What is acceleration? (article) | Kinematics | Khan Academy
Velocity describes how position changes; acceleration describes how velocity changes. Two layers of change!
A 3-mode, Variable Velocity Jet Model for HH 34
Variable ejection velocity jet models can qualitatively explain the appearance of successive working surfaces in Herbig-Haro (HH) jets. This paper presents an attempt to explore which features of the HH-34 jet can indeed be reproduced by such a mod...
Entrainment into particle-laden turbulent plumes
We use laboratory experiments to investigate the entrainment of ambient fluid into an axisymmetric turbulent plume that contains dense particles with a settling velocity that is considerably smaller than the plume velocity. We consider the effect of...
Acoustic measurement of potato cannon velocity
This article describes measurement of potato cannon velocity with a digitized microphone signal. A microphone is attached to the potato cannon muzzle and a potato is fired at an aluminum target about 10 m away. The potato's flight time can be deter...
Discovery of Multiple Ultra-Broad-Velocity Molecular Features Associated with the W44 Mole…
We report the discovery of multiple compact molecular features exhibiting extremely broad velocity widths toward the W44 molecular cloud. ALMA CO $J$=3--2 data reveal eight ``Petit--Bullets'' surrounding the previously known ``Bullet.'' Each Petit--B...
Emission-Line Eclipse Mapping of Velocity Fields in Dwarf-Nova Accretion Disk
We propose a new method, emission-line eclipse mapping, to map the velocity fields of an accretion disk in position space. Quiescent dwarf novae usually exhibit double-peaked emission line profiles because of disk rotation. Since a part of the disk...
The stellar velocity dispersion in the inner 1.3 disk scale-lengths of the irregular galax…
We present measurements of the stellar velocity dispersion in the inner 1 arcmin radius (1.3 disk scale-lengths) of the irregular galaxy NGC 4449 determined from long-slit absorption-line spectra. The average observed dispersion is 29 +/-2 km/s, th...
Negative Group Velocity
The group velocity for pulses in an optical medium can be negative at frequencies between those of a pair of laser-pumped spectral lines. The gain medium then can amplify the leading edge of a pulse resulting in a time advance of the pulse when it...
Singularity formation for a fluid mechanics model with nonlocal velocity
We study a 1D fluid mechanics model with nonlocal velocity. The equation can be viewed as a fractional porous medium flow, a 1D model of the quasi-geostrophic equation, and also a special case of Euler-Alignment system. For strictly positive smooth i...
Study of the Dynamic Coupling Term (μ) in Parallel Force/Velocity Actuated Systems
Presented in this paper is an actuator concept, called a Parallel Force/Velocity Actuator (PFVA), that combines two fundamentally distinct actuators (one using low gear reduction or even direct drive, which we will call a Force Actuator (FA) and the...
Blank Velocity Banking Spreadsheet : r/velocitybanking - Reddit
Blank Velocity Banking Spreadsheet So I'm very pleased my spreadsheet has been requested many times (that it's free probably helped somewhat). It's been a pain to have to ask for email addresses …
Brighter galaxy bias: underestimating the velocity dispersions of galaxy clusters
We study the systematic bias introduced when selecting the spectroscopic redshifts of brighter cluster galaxies to estimate the velocity dispersion of galaxy clusters from both simulated and observational galaxy catalogues. We select clusters with Ng...
Velocity independent constraints on spin-dependent DM-nucleon interactions from IceCube an…
Adopting the Standard Halo Model (SHM) of an isotropic Maxwellian velocity distribution for dark matter (DM) particles in the Galaxy, the most stringent current constraints on their spin-dependent scattering cross-section with nucleons come from the...
A Tale of Two Butterflies: An Exact Equivalence in Higher-Derivative Gravity
We prove the equivalence of two holographic computations of the butterfly velocity in higher-derivative theories with Lagrangian built from arbitrary contractions of curvature tensors. The butterfly velocity characterizes the speed at which local per...

Higher-order mean velocity profile in the convective atmospheric boundary layer
The higher-order mean velocity profile in the convective atmospheric boundary layer (CBL) is derived using the method of matched asymptotic expansions. The universal expansion coefficients are obtained using field measurement data. The profile accoun...
Multi-Vehicle Velocity Estimation Using IEEE 802.11ad Waveform
Wireless communication systems are to use millimeter-wave (mmWave) spectra, which can enable extra radar functionalities. In this paper, we propose a multi-target velocity estimation technique using IEEE 802.11ad waveform in a vehicle-to-vehicle (V2V...
