NEET2010PhysicsWork, Power and EnergyActual
A particle of mass M starting from rest undergoes uniform acceleration. If the speed acquired in time T is v , the power delivered to the particle is
Options
- AMv ^2 ~T
- B1 2 Mv ^2 ~T ^2
- CMv ^2 ~T ^2
- D1 2 Mv ^2 ~T
Correct answer
D. 1 2 Mv ^2 ~T
Step-by-step solution
The kinetic energy of particle = 1 2 Mv ^2 aligned Power & = Energy Time P & = 1 2 Mv ^2 ~T aligned
