A projectile is fired from ground level with an initial velocity of 50m/s and an initial angle of 30degree. Assuming g= 9.8 m/s*2, find:
(a) The projectile total time of flight.
(b) The maximum height attained
(c) The total horizontal traveled
(d) The final horizontal and vertical velocities just before it hits the ground

t= 2vₒ•sinα/g,
h= vₒ²•sin²α/2g,
L=vₒ²•sin2α/g,
v(fin) =v(init)
v(x)=v(x0) =v(0)•cosα
v(y)=v(y0)=v(0)•sinα
