Momentum and CollisionHard
Question
A particle of mass M, starting from rest, undergoes uniform acceleration. If the speed accuired in time T is V, the power delivered to the particle is ?
Options
A.
B.
C.
D.
Solution
Power delivered in time T is
P = F.V = MaV
or P = MV
⇒ PdT = MV dV
⇒ PT =
or P = 
P = F.V = MaV
or P = MV
⇒ PdT = MV dV⇒ PT =
or P = Create a free account to view solution
