Question
a 50.0 kg child takes a ride on a ferris wheel that rotates with a tangential speed of 1.2 m/s. find the centripetal force that maintains the circular motion of the child if the distance from the center of the ferris wheel is 16.0 m.
$f_c = ____ n$
3.75 n
4.5 n
450 n
16 n
Step1: Identificar la fórmula
La fórmula para la fuerza centrífuga es $F_c = \frac{mv^{2}}{r}$, donde $m$ es la masa, $v$ es la velocidad tangencial y $r$ es el radio.
Step2: Sustituir valores
Dado que $m = 50.0$ kg, $v = 1.2$ m/s y $r = 16.0$ m, sustituimos en la fórmula: $F_c=\frac{50.0\times(1.2)^{2}}{16.0}$.
Step3: Realizar cálculos
Primero calculamos $(1.2)^{2}=1.44$. Luego, $50.0\times1.44 = 72$. Finalmente, $\frac{72}{16.0}=4.5$ N.
