the velcoity of a trian incrreases at a ...

the velcoity of a trian incrreases at a constant rate `alpha` from 0 to v and then remains constant for same interval and then finally decreases to zero at constant rate `beta`.if the total distance coverd by the the particle x,then show that the total time taken will be
`tx/v+v/2[1/alpha + 1/beta]`.
