If <em>v</em> is the truck's final velocity, then
<em>v</em>² - (2.0 m/s)² = 2 * (2.00 m/s²) * (400.0 m)
<em>v</em>² = 1604 m²/s²
<em>v</em> = 40.05 m/s ≈ 40 m/s
Answer:
Explanation:
<u>Velocidad Angular</u>
Un objeto en rotación con movimiento circular uniforme describe ángulos iguales en tiempos iguales.
La velocidad angular ω es una magnitud que mide el ángulo θ que gira una partícula en cierto tiempo t, según la fórmula:
La velocidad angular suele medirse en radianes/segundo, revoluciones/minuto, grados/segundo, etc.
Si la rotación es uniforme, el valor de la velocidad angular es constante.
La rueda del problema a resolver se desplaza θ=15 rad en t=0.2 s, así que su velocidad angular es:
Answer:
4.5 Cm

Answer:
a) Magnitude = 1.03 m/s², Direction: south
b)
Explanation:
a) The magnitude and direction of the acceleration can be calculated using the following equation:
(1)
Where:
: is the final speed = 9.40 m/s
: is the initial speed = 13.0 m/s
t: is the time = 3.50 s
Solving equation (1) for a, we have:
Hence, the magnitude of the acceleration is 1.03 m/s² and the direction of the bird's acceleration is the opposite of the initial velocity direction, which means that the bird is decelerating.
b) The final velocity of the bird can be found using the same equation 1:
Therefore, the bird’s velocity after an additional 1.20 s has elapsed is 8.16 m/s.
I hope it helps you!
