Answer:
1.63
Explanation:
If you have the following options:
<u>A. 1.63</u>
B. 1.50
C. 1.49
D. 1.33
E. 1.02
Answer:
Explanation:
a ) 12.0 lbs - mass
b ) .34 g - mass
c ) 120 kg - mass
As lbs , g and kg are units of mass , these things represent mass . lbs is FPS unit of mass and kg is SI unit . g is CGS unit of force .
d ) 1600 kN It represents force because kN or kilonewton is unit of force .
e ) it represents , length or distance because m or metre is unit of length .
f ) 411 cm It represents length or distance because cm is smaller unit of length
g ) 899 MN or million newton . Like d ) It also represents force . Million newton is higher unit of force .
Answer:2.17 rad/s
Explanation:
Given
Each wheel has moment of inertia ![I=0.76 kg-m^2](https://tex.z-dn.net/?f=I%3D0.76%20kg-m%5E2)
Linear speed speed ![v=15 m/s](https://tex.z-dn.net/?f=v%3D15%20m%2Fs)
angular speed of tire ![\omega =50 rad/s](https://tex.z-dn.net/?f=%5Comega%20%3D50%20rad%2Fs)
moment of inertia of motorcycle ![I_2=35 kg-m^2](https://tex.z-dn.net/?f=I_2%3D35%20kg-m%5E2)
Initial moment of inertia ![I_1=2\times 0.76=1.52 kg-m^2](https://tex.z-dn.net/?f=I_1%3D2%5Ctimes%200.76%3D1.52%20kg-m%5E2)
Due to absence of external Torque we can Conserve Angular Moment of inertia
![l_1\omega _1=I_2\cdot \omega _2](https://tex.z-dn.net/?f=l_1%5Comega%20_1%3DI_2%5Ccdot%20%5Comega%20_2)
![2\times 0.76\times 50=35\times \omega _2](https://tex.z-dn.net/?f=2%5Ctimes%200.76%5Ctimes%2050%3D35%5Ctimes%20%5Comega%20_2)
![\omega _2=2.17\ rad/s](https://tex.z-dn.net/?f=%5Comega%20_2%3D2.17%5C%20rad%2Fs)
