Answer:
The answer is
<h2>56,000 kgm/s</h2>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
m = 1400 kg
v = 40 m/s
We have
momentum = 1400 × 40
We have the final answer as
<h3>56,000 kgm/s</h3>
Hope this helps you
Answer:
Final angular velocity = 2.15rad/s
Explanation:
The final angular velocity can be determined using the equation:
L=Ii × wi
L= (Ii + II) × wf
Where I is the moment of inertia of the 2nd cylinder and wf is the final angular velocity.
Given:
Ii=12.6kgm^2
I=41.8kgm^2
Wi=9.28rad/s
Ii ×wi= (Ii + I)×wf
12.6×9.28 = (12.6+41.8)×wf
116.93= 54.4wf
Wf=116.93/54.4
Wf= 2.15rad/s
Answer:
nvwngviuvnbowibnoijbdofij
Explanation:
The magnification formula is:
M = H (i)/H (o) = -D (i)/D (o)
In other words, the ratio of the image distance and object distance to the ratio of the image height and the object height.
