Show that v^(2)=v_(0)^(2)+2ax graphical method.

Show that x=v_(0)t+1//2at^(2) by graphical method.

Show that v=romega .

(a) Show that for a projectile the angle between the velocity and the x - axis as a function of time is given by theta(t)="tan"^(-1)((v_(0y)-"gt")/(v_(@)x)) (b) Shows that the projection angle theta_(@) for a projectile launched from the origin given by theta_(0)=tan^(-1)((4h_(m))/(R)) where the symbols have their usual meaning.

Show graphically, the variation of the de-Broglie wavelength ( lambda ) with the potential (V) through which an electron is accelerated from rest.
