Un objeto cae accidentalmente de un vehículo con una velocidad de
50 km / hy recorra 20 m antes de detenerse.
Calcular:
a) La aceleración:
b) El tiempo que tarda en detenerse:
Responder:
1.439 s
-9,645 m / s²
Explicación paso a paso:
Dado que:
Velocidad en m / s = (50 * 1000) / 3600 = 13.899 m / s
Distancia (d) = 20
Tiempo = distancia / velocidad
Tiempo = 20 / 13.889
Tiempo = 1.439 s
Aceleración (a):
Cambio de velocidad / tiempo empleado
= (0 - 13,889) / 1,439
- 13.889 / 1.439
= -9,645 m / s²
Answer:
1
Step-by-step explanation:
Given parameters:
Length of ribbon =
yards
Unknown:
Maximum number of
yards that can be cut = ?
Solution:
Maximum number of length that can be cut;
=
Maximum number of length =
Maximum number of length =
x
= 1
The maximum number of
yards that can be cut is 1
Hello there!
10/110 is a rational number because it can be expressed in the form p/q (where p is the numerator and q is the denominator)
<h2>Therefore, 10/110 is a rational number.</h2>
Hope this helps you!
