Desde el borde de una mesa, se lanza horizontalmente un cuerpo A, con, con cierta velocidad inicial, y simultáneamente se deja caer desde el mismo punto un cuerpo B. ¿Cuál de los dos llegará primero al piso? Explica.

i think the answer would be b

need to see circuit to get time constant

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
