Answer:
The correct answer to the following question will be Option A (I1 > I2).
Explanation:
Method for moment of inertia because of it's viewpoint including object at a mean distance "r" from the axis is,
⇒ mr²
<u>For Case 1:</u>
Let the length of a rod be "r".
The axis passes via the middle of that same rod so that the range from either the axis within each dumbbell becomes "".
Now,
Now total moment of inertia = sum of inertial moment due to all of the dumbbell
⇒
⇒
<u>For Case 2:</u>
Axis moves via one dumbbell because its range from either the axis becomes zero (0) and its impact is zero only at inertia as well as other dumbbell seems to be at a range "r" from either the axis
Now,
Total moment of inertia = moment of inertia of dumbbell at distance "r".
And now we can infer from this one,
⇒
So that "I1 > I2" is the right answer.
Answer:
a)v=5.81 m/s
b)N= 831.77 N
Explanation:
Given that
m = 39 kg
r= 2.98 m
T= 416 N
a)
Lets take speed of the boy at the lowest position is v m/s
The radial force Fc
The tension in the chain is T
Now by putting the values
v²=33.77
v=5.81 m/s
b)
Lets take normal force = N
Now by putting the values
N= 831.77 N
Answer:
I'm pretty sure your speed relative to the ground would be 110 meters per second. However that is just a guess and I'm not 100% sure.
The type of collision in which the object stick with one another is a perfectly inelastic one. For inelastic collisions, the momentum is preserved such that,
M1 = M2
Momentum is the product of the objects mass and velocity. In this item, we are given that the after sticking with one another, the trucks moved at a speed half of the speed of the originally moving one. Hence, the trucks must have the same load which is equal to saying that they have equal masses.
