Questions
A body is moving unidirectionally under the influence of a source of constant power supplying energy. Which of the diagrams shown below correctly shows the displacement time curve for its motion ?
detailed solution
Correct option is B
P=F.v=constant mdvdtv=P mdv.v =Pdt ∫mvdv=∫Pdt mv22=Pt v=2Ptm dxdt=2Ptm ∫dx=2Ptmdt x=2Pmt32x is proportional to t32dxdt=32t12 Since dx/dt = v = slope increases with time 2 is correct option.Talk to our academic expert!
