Answer:
I_weight = M L²
this value is much larger and with it it is easier to restore balance.I
Explanation:
When man walks a tightrope, he carries a linear velocity, this velocity is related to the angular velocity by
v = w r
For man to maintain equilibrium needs the total moment to be zero
∑τ = I α
S τ = 0
The forces on the home are the weight of the masses, the weight of the man and the support on the rope, the latter two are zero taque the distance to the center of rotation is zero.
Therefore the moment of the masses and the open is the one that must be zero.
If the man carries only the bar, we could approximate it by two open one on each side of the axis of rotation formed by the free of the rope
I = ⅓ m L² / 4
As the length of half the length of the bar and the mass of the bar is small, this moment is small, therefore at the moment if there is some imbalance it is difficult to recover.
If, in addition to the opening, each of them carries a specific weight, the moment of inertia of this weight is
I_weight = M L²
this value is much larger and with it it is easier to restore balance.
Answer:
The mass of the apples in the box are 1145.95 lb.
Explanation:
Given that,
Width = 3.5 ft
length = 3.5 ft
Depth = 2.75 feet
Density = 49.3 lb/ft³
We need to calculate the volume
Using formula of volume

Put the value


We need to calculate the mass
Using formula of density


Put the value into the formula


But porosity is 31 % so apples is 69% mass of total container.
So, Total mass in pounds is


Hence, The mass of the apples in the box are 1145.95 lb.
Speed = distance/time taken
1484 = distance/3
Distance = 1484 x 3
Distance = 4452 m
