If \( T \) is the total time of flight, \( h \) is the maximum height and \( R \) is the range for horizontal motion, the \( x \) and \( y \) co-ordinates of projectile motion and time \( t \) are related as
(1) \( y=4 h\left(\frac{t}{T}\right)\left(1-\frac{t}{T}\right) \)
(2) \( y=4 h\left(\frac{x}{R}\right)\left(1-\frac{x}{R}\right) \)
(3) \( y=4 h\left(\frac{T}{t}\right)\left(1-\frac{T}{t}\right) \)
(4) \( y=4 h\left(\frac{R}{x}\right)\left(1-\frac{R}{x}\right) \)
