(1) Question: Deriving the Equations of Motion of a Projectile Fired (Air resistance is neglected) First, Newton mechanics; There is no force acting on the object in the x direction. y Vo mx = F = 0 In the y direction, there is only gravitational acceleration, in the opposite direction. my -- F, =- mg=y=- 9 x = 0= x = constant = V.cose = x = V cost.t y”=- g=y' =- gt + c =>y =-2gt² + ct +cz =- (2) (2) y t = 0= y(0) = Vsine = Vsine t = 0= y(0) = 0 - įgt? + Vsint + +2 = 0 y =- £gt? + Vsint (a) Obtain the x and y equations in polar coordinates. x (x,y) k r = x + tant = ? (b) Obtain the same equation with the use of the transformation below. 2 r = Vx* - y, tant = xy
