Answer:
4. B) 69N
5. B) 7.2kg
Explanation:
Dados los siguientes parámetros;
Masa = 7kg
Peso = 71N
La aceleración debida a la gravedad es igual a 9.8m/s².
a. Para determinar el peso de la siguiente masa;
Matemáticamente, el peso viene dada por la fórmula;
Peso = masa * aceleración debida a la gravedad
Peso = 7 * 9.8
Peso = 68.6 ≈ 69 Newton.
b. ¿Cuál es la masa sobre la tierra de un objeto que pesa.
Peso = masa * aceleración debida a la gravedad
71 = masa * 9.8
Masa = 71/9.8
Masa = 7.2 Kilograms.
It is Potential energy it's at rest
Question: 18 kilogram Mass Block rest on level surface if the coefficient of static friction between the Block and the surface is 0.6 what horizontal force is required to just move the blcok ( take gravity as 10m/s2
)
Answer:
108 N
Explanation:
From the question,
Applying
F' = mgμ................ Equation 1
Where F' = Frictional force = horizontal force required to just move the block, m = mass of the block, g = acceleration due to gravity, μ = coefficient of static friction.
From the question,
Given: m = 18 kg, μ = 0.6, g = 10 m/s²
Substitute these values into equation 1
F' = 18×0.6×10
F' = 108 N
Answer:
v_average = (d₂-d₁) / Δt
this average velocity is not necessarily the velocity of the extreme points,
Explanation:
To resolve the debate, it must be shown that the two have part of the reason, the space or distance between the two points divided by time is the average speed between the points.
v_average = (d₂-d₁) / Δt
this average velocity is not necessarily the velocity of the extreme points, in the only case that it is so is when there is no acceleration.
Therefore neither of them is right.
Answer:
8 N
Explanation:
Using the equation F=ma (F: force/ m: mass in kg/ a: acceleration),
F = (800/1000)(10)
F = 8 N
