del tema de fuerza centripeta

1.- Un chico va en bicicleta a 10m/s por una curva plana de 200m de radio.
a) ¿Cuál es la aceleración?
b) si el chico y la bicicleta tienen una masa total de 70kg, ¿Qué fuerza se necesita para producir esta aceleración?

Sagot :

Lanuel

Answer:

a. C = 0.5 m/s²

b. F = 35 Newton

Explanation:

Given the following data;

Radius, r = 200 m

Velocity, v = 10 m/s

Mass, m = 70 kg

a. To find the centripetal acceleration;

Mathematically, centripetal acceleration is given by the formula;

C = v²/r

Where:

C is the centripetal acceleration

v is the velocity

r is the radius

Substituting into the formula, we have;

C = 10²/200

C = 100/200

C = 0.5 m/s²

b. To find the force;

F = mv²/r

F = (70*10²)/200

F = (70 * 100)/200

F = 7000/200

F = 35 Newton
