A ball was projected at an angle 30 degrees above the horizontal with an initial velocity ,V, in a vacuum. Another identical ball was projected at 60 degrees to the horizontal from the same point in a vacuum.
1. Show that both balls had the same range.
2.Sketch ,on the same axes, the path followed by the ball.

in this type of projectile question there are 2 angles of projection which result in the same range*
one will be a low trajectory where the projectile has a high horizontal component of velocity and the other will be a high trajectory where the lower horizontal component of velocity is compensated by a greater amount of flight time.

*except 45 degrees

if you're able to do projectile calculations you should just be able to compare the results for the 2 projectiles and see if they're the same or not.
