An automobile of mass m accelerates, starting from rest. The engine supplies constant power P, show that the velocity is given as a function of time by `v=((2Pt)/(m))^(1//2)` |
|
Answer» Power,P=constant Work done up to time t is W =Pt From work energy theorem, `W=DeltaKE " or "Pt=(1)/(2)mv^(2)` `:. " " v=((2Pt)/(m))^(1//2)` |
