The acceleration of an object in motion is given by the vector (t)=(2t,e^t). If the object's initial velocity was v(0)=(2,0), which is the velocity vector at any time t? ( ) A. (v )(t)= t^2,e^t+1 B. v(t)= t^2+2,e^t C. v(t)=(t^2+2,e^t-1) D...
Find the position vector R(t) and velocity V(t) given the acceleration A(t)=2e - ti + 20\cos(2t)j + 48t^2k and the initial velocity vector V(0)=2i - j - 3k and initial position vector R(0)= i +...
The average displacement vector for the Particle 2 was found to be 29.0 ± 0.34 pm in magnitude along the direction of (0.61, −0.78, 0.10), and the net polarization per unit cell was estimated to be 0.61 ± 0.20 C m−2. The overall magnitude of the displacemen...
Tangential and Normal Components of Acceleration Theorem Letr(t)r(t)be a vector-valued function that denotes the position of an object as a function of time. Thena(t)=r′′(t)a(t)=r″(t)is the acceleration vector. The tangential and normal components of accelerationaTaTandaNaNare given...
where u is the velocity vector, P the dynamic pressure, η the viscosity, \(\dot \varepsilon\) the strain-rate tensor, δT the temperature perturbation, g the gravitational acceleration vector, T the temperature, t the time, H the internal heat generation rate and Ci the composition used ...
The average pulse height must decrease at −5% and not increase significantly at +5% and +10% HV for the HV setting to be correct. Table 5 summarizes the key properties for MMIA photometers. 4 Data Processing Unit 4.1 Hardware The ASIM payload computer, the Data Handling Power Unit (DH...
2. The optimal strategies: (vector) functions u∗(x) and v∗(x) defined over X. They may or may not be unique. In the latter event we might be interested in obtaining a complete set of all optimal strategies or we might be satisfied with just one. 3. The optimal paths: …These...
The data set of two inputs, wind speed and wave elevation has been considered to train the ANN. These models replicate the structural behavior of a FOWT and its power dynamics with an output vector defined as: $$\begin{aligned} v_k^{\prime ~T}= \left[ {Pitch} ~~{Fore\text {-}...
In Table 1, we summarized the average values of the speed modulus and the angle towards the ball of all cases studied. Figure 14 Scatter plot of the average angle between the velocity of the players and their distance to the ball vector (see Fig. 1 for details). Goalkeepers (a), ...
