Which of the following functions is a solution for the differential equation `dy/dx-14x=0`?
`a) y=7x^2`
`b) y=7x^3`
`c) y=x^7`
`d) y=14x`

Text Solution

Verified by Experts

The correct Answer is:
A, D
A whel has `I=0.500 kg-m^2,r=0.2m`
`omega=20rad/s`
statioN/Ary particle =0.2 kg
Therefore `I_1omega_1=I_1omega_2`
[since exterN/Al torque =0]
`rarr 0.5x20=90.5+0.2xx0.22)omega_2`
`rarr omega_2=10/0.508`
`=19.69=19.7rad/s`
