Question

Si la rapidez lineal de un móvil que se desplaza con MCU se triplica y el radio se mantiene constante, entonces la fuerza centrípeta:

Answer 1

F' = 9 F

Step-by-step explanation:

The question says that, "If the linear speed of a mobile moving with MCU is tripled and the radius remains constant, then the centripetal force:"

The formula for the centripetal force is given by :

`F=\frac{mv^2}r{}`

Where

m is the mass of the object

v is the velocity

r is the radius of path

If the linear speed us tripled, v' = 2v, r = constant, then the new centripetal force is given by :

`F'=\frac{mv'^2}r{}\\\\F'=(m(3v)^2)/(r)\\\\=(mv^2)/(r)* 9\\\\F'=9F`

So, the new force becomes 9 times of the initial force.
