An object has an initial velocity of 15 m/s in a constant acceleration of 4 m/s^2. How long will it take before it's final velocity is equal to three times its initial velocity? What is the velocity measuring unit? What is the dimensional formula of velocity?
In the following formula, v is initial velocity, v_e is ending velocity, a is acceleration. v_i is 7 meters per second, a is 8 meters per second squared, and d is 2 meters, where v_e? () A. 9 meters per second B. 5.74 meters per second C. 6.25 meters per second D. 4.12 ...
Example 2 Initial Velocity of a Punt A football is punted 51 m and is airborne for 4.5 s. Let us determine (a) the magnitude of the initial velocity if θ = 63°, and (b) how far the football would travel horizontally if launched with the same initial velocity but with θ = 45°...

[3]), that uncertainty appears through the initial velocity value. Since the one-dimensional version of Eq. (1.1) was proposed by Woinowsky-Krieger [28], there have been many researches focused on the properties of the solutions such as stability or energy decay, including studies on ...
aC Zhu and R Rajamani C朱和R Rajamani [translate] aTo the ship equipment whose mass is larger than 5 tons, the initial shock acceleration and velocity should be reduced, the reduction formula is as follows: 对大量大于应该减少的船设备5吨、最初的震动加速度和速度,减少惯例是如下: [translate] ...
To test the effect of the vision information combined with the gravity recognition algorithm of moment of inertia, as described in "Controller design" section, a three-dimensional vision and gravity compensation method was applied to grasp stone. In the experiments with a 1.0 m long stone object...
Under the Bargann constraint between the potentials and the eigenfunctions, the spectral problem is nonlinearized as a finite-dimensional completely integrable Hamiltonian system. The involutive representation of the solutions for the Kaup–Newell-type hierarchy is also presented. In addition, an N-...

[3] proposed a two-dimensional model which is called “hyperbolic Boussinesq system” and describes an incompressible velocity vector field, a simplified Biot–Savart law, and a simplified term modeling buoyancy. The authors showed that finite time blow-up happens for a natural class of initial ...
