Answer:

3620.9 Watts

Explanation:

So first you want to find the work (J) and to find the work you need to multiply force (N) times distance (m).

348.0*33.4=11623.2 J

After that you want to find the power (Watt) and to find the power you need to divide the work (J) by the time (s).

11623.2/3.21=3620.9 Watts

How does the voltage applied to the electric motor affect the coil's number of rotations and its rotational direction
sleet_krkn [62]
Higher voltage means faster rotation.  Changing the voltage polarity changes the direction of the motor.

Kid A has jumped off the sled! (RIP)
balandron [24]

Answer:

46.45 m/s

Explanation:

Total momentum before jump = Total momentum after jump

11.7 * ( 36.7 + 45.2 ) = ( 36.7 * (-31.1) ) + ( 45.2 * v )

v*45.2 - 1141.37 = 958.23

v = 2099.6/45.2 = 46.45

Se deja caer un objeto desde la cornisa de una casa la cual tarda en llegar al suelo 645/500 segundos. ¿Cúal es la altura de la
salantis [7]

8.15m. La altura de la casa de la cual se deja caer un objeto que tarda en caer \frac{645}{500}s es de 8.15m.

La clave para resolver este problema es mediante caída libre, la velocidad inicial del objeto es 0 por lo que podemos calcular la altura h de la casa mediante la relación h= \frac{gt^{2}}{2}.

Conocemos la gravedad g=9.8\frac{m}{s^{2}} y el tiempo en que tarda en caer el objeto t=\frac{645}{500}s, sustituyendo los valores tenemos que:

h=\frac{(9.8\frac{m}{s^{2}})(\frac{645}{500}s)^{2}}{2}=8.15m

Lena [83]

Answer: x = 0.957 m

Explanation:

F = ma

d = ½at²

a = 2d/t²

F = m2d/t²

F = kx

kx = m2d/t²

x = 2md/kt²

x = 2(8.86)(4.36) / (471(0.414²))

x = 0.957036...
