Answer» The graph between maximum height attained and the time of flight of a particle THROWN VERTICALLY upward with a variable SPEED To Find : Shape of Grapha. straight lineb. PARABOLAC. ellipsed. hyperbolaSolution Let say speed = UTime to reach maximum height = t using V = U + at => 0 = U - gt=> t = U/gTime of flight = 2t= 2U/gS = ut + (1/2)at²H = U(U/g) + (1/2)(-g)(U/g)²=> H = U²/g - U²/2g=> H = U²/2g => H = U . U/2g => H = UT/4=> H = (U/4) T T = 2U/gH = U²/2gH ∝ T²Hence Parabolagraph between maximum height attained and the time of flight of a particle thrown vertically upward with a variable speed will be parabola Learn More:The graph between maximum height attainedbrainly.in/question/27353674 |
