Area under speed-time curve gives

Answer»

distance
velocity
acceleration
none of these

Solution :Let L = angular MOMENTUM
`tau = (dL)/(dt) rArr dL = tau dt`
For constant torque
`Delta L = tau Delta I = I Delta OMEGA rArr Delta L = I omega ("if" omega_(1) = 0)`
Rotational kinetic ENERGY `= (1)/(2) Iomega^(2) = ((Delta L)^(2))/(2I)`
