Answer:
Si logra alcanzar el bus.
Explanation:
Para poder solucionar este problema debemos de tener en cuenta que Alicia corre a velocidad constante para poder alcanzar el bus. La formula de la cinematica que tiene en cuenta la velocidad constante es la siguiente:

donde:
Xf = Ubicacion del punto donde se encuentra el bus [m]
Xo = Ubicacion desde donde esta Alicia [m]
v = velocidad constante = 5 [m/s]
t = tiempo [s]
Xf - Xo = 15 [m]
15 = 5*t
t = 3 [s]
Ahora con el tiempo podemos encontrar la velocidad del bus por medio de la siguiente ecuacion de cinematica para la aceleracion constante:

donde:
Vf = velocidad del bus despues de los 3 [s]
Vi = velocidad inicial = 0
a = aceleracion = 0.5 [m/s^2]
Vf = 0 + (0.5*3)
Vf = 1.5 [m/s]
La velocidad del bus es menor que la velocidad de Alicia, por ende Alicia alcanzara el bus.
If you travel 30 miles somewhere and then come home again your distance is 60 miles. Your displacement is 0 because it is the ending position minus the beginning position, which are the same place (home). In other words, displacement is a vector and distance is a scalar.

Answer:

Explanation:
Consider two particles are initially at rest.
Therefore,
the kinetic energy of the particles is zero.
That initial K.E. = 0
The relative velocity with which both the particles are approaching each other is Δv and their reduced masses are

now, since both the masses have mass m
therefore,

= m/2
The final K.E. of the particles is

Distance between two particles is d and the gravitational potential energy between them is given by

By law of conservation of energy we have

Now plugging the values we get



This the required relation between G,m and d
