Un barco va a una velocidad de 45 ml/h, luego el capitán ordena acelerar hasta que la velocidad hasta que la velocidad sea de 60
Sophie [7]

Pregunta completa:

Un barco va a una velocidad de 45 ml/h, luego el capitán ordena acelerar hasta que la velocidad hasta que la velocidad sea de 60 mll/h. si la operación dura 30 minutos.

A cual fue la aceleracion?

B qué distancia recorre?

Responder:

30 millas / hora

26.25 mi

Explicación:

Dado que :

Velocidad inicial, u = 45 mi / hr

Velocidad final, v = 60 mi / hr

Tiempo, t = 30 minutos = 30/60 = 0,5 h

Aceleración, a = cambio de velocidad con el tiempo;

a = (v - u) / t

a = (60 - 45) / 0,5

a = 15 / 0,5

a = 30 millas / h²

Recorrido de distancia, S

S = ut + 0.5at²

S = 45 (0,5) + 0,5 (30) (0,5²)

S = 22,5 + 3,75

S = 26,25 millas

Two billiard balls of equal mass are traveling straight toward each other with the same speed. They meet head-on in an elastic c
Rus_ich [418]

Answer:

0 kg m/s before and after collision

Explanation:

Let m, v be the mass and speed of the 2 balls, respectively, before the collision. Since they have the same mass and same speed but in opposite direction, the total momentum of the system would be:

P = mv - mv = 0 kg m/s

As the collision is elastic. The total momentum after the collision is the same as the total momentum before the collision, which is 0.

Una grúa está subiendo una caja de 1000 kg atada a una cadena. La caja, que inicialmente está en reposo, incrementa su velocidad
BabaBlast [244]

Answer:

40 metros en 10 segundos.

Explicación:

Una grúa está levantando una caja de 1000 kg atada a una cadena y la caja, que inicialmente está en reposo, aumenta su velocidad en 4 m / s por segundo, por lo que si la región de colocación está a 40 metros de distancia, la grúa tarda 10 segundos en completar el proceso. tarea de movimiento y colocación de la caja. La grúa se utiliza para levantar y mover cargas pesadas, máquinas, materiales y mercancías para diferentes propósitos. Entonces el trabajo realizado por la grúa depende de la velocidad y la distancia de colocación.
