9. Calcule el valor de la fuerza que experimenta un ascensor cuando levanta 150 kg en los siguientes casos: a) Cuando asciende con una aceleración de 4 m/s2 b) Cuando asciende con una aceleración de 6 m/s2 c) Explique: ¿Por qué el ascensor experimenta diferentes aceleraciones si levanta el mismo peso en ambos casos?
Answer:
a) La fuerza neta que experimenta un ascensor cuando asciende con una aceleración de 4 metros por segundo al cuadrado es 600 newtons hacia arriba.
b) La fuerza neta que experimenta un ascensor cuando desciende con una aceleración de 6 metros por segundo al cuadrado es 900 newtons hacia abajo.
c) Por la fuerza de tensión sobre el cable del ascensor.
Step-by-step explanation:
a) La fuerza neta experimentada por el ascensor ([tex]F[/tex]), en newtons, es:
[tex]F = m\cdot a[/tex] (1)
Donde:
[tex]m[/tex] - Masa, en kilogramos.
[tex]a[/tex] - Aceleración, en metros por segundo cuadrado.
Si sabemos que [tex]m = 150\,kg[/tex] y [tex]a = 4\,\frac{m}{s^{2}}[/tex], entonces la fuerza neta del ascensor es:
[tex]F = m\cdot a[/tex]
[tex]F = 600\,N[/tex]
La fuerza neta que experimenta un ascensor cuando asciende con una aceleración de 4 metros por segundo al cuadrado es 600 newtons hacia arriba.
b) Si sabemos que [tex]m = 150\,kg[/tex] y [tex]a = -6\,\frac{m}{s^{2}}[/tex], entonces la fuerza neta del ascensor es:
[tex]F = m\cdot a[/tex]
[tex]F = -900\,N[/tex]
La fuerza neta que experimenta un ascensor cuando desciende con una aceleración de 6 metros por segundo al cuadrado es 900 newtons hacia abajo.
c) De manera simplificada, el ascensor experimenta dos fuerzas que definen la fuerza y aceleración netas: (i) La fuerza de tensión sobre el cable que traslada el ascensor y el peso total del ascensor, opuesta a la anterior y en función de la aceleración gravitacional. Puesto que la masa no varía en ningún caso, se concluye que el peso es constante, entonces la diferencia de valores se debe a la fuerza por tensión del cable. En el descenso, es fuerza es menor que en el ascenso.
61 = m + - 8 what would be m
Answer:
m would be 69!
Step-by-step explanation:
61 = m - 8
61 + 8 = m - 8 + 8
69 = m
Answer: 69
Step-by-step explanation:
61=m+-8
as plus minus equals to minus so its -8
61=m-8
m=61+8
m=69

7. 180 -92 -67 =21. 180-21 = 159
8.180-144 = 36 + 94 = 130 180-130 = 50
Answer:
Step-by-step explanation:
TWO RULES:
⊳ Angles in a triangle add up to 180
⊳ Angles on a straight line also add up to 180
=================================================================
QUESTION 1
92 + 67 + x = 180
x + 159 = 180
x = 21
180 - 21 = 159
? = 159
=================================================================
QUESTION 2
144 + x = 180
x = 36
94 + 36 + ? =180
130 + ? =180
? = 50
=================================================================

Chole's meal cost
$40 + 5% × $40 + 20% × $40
= $40 + $2 + $8
= $50

Bill plans to save for a pair of headphones that are 89.00.The sales tax rate is 8% how much will bill need to save
Answer: 96.12
Step-by-step explanation:
The amount that Bill will need to save will be for the cost of the headphones and the sales tax that will be applied. This will be:
= 89 + (8% × 89)
= 89 + (0.08 × 89)
= 89 + 7.12
= 96.12
Therefore, Bill will need to save 96.12.
