    It’s mathematically impossible to send an object into orbit just from energy imparted on the ground. Depending on the speed you launch it, either it falls back down or it flies off into space.
    To achieve orbit you need a circularization burn at the highest point of your trajectory.

    Or as Scott Manley put it:
    “Getting into space is easy. Getting into orbit is hard.”
