Questions
A body of mass m accelerates uniformly from rest to v, in time t, . As a function of t, the instantaneous power delivered to the body is
a
mv1tt1
b
mv12tt1
c
mv1t2t1
d
mv12tt12
detailed solution
Correct option is D
We know that, v =u + at∴ v1=0+at1 or a=v1/t1 ustantaneous velocity, v = o t : ∴ P=Fv=ma×at =ma2t =mv12t12⋅tTalk to our academic expert!
