Twice as far. Here's the reason The maximum height when you throw vertically is V^2/2g. (That is easily proven using conservation of energy) The RANGE X at any angle A is 2 sinAcosA/V^2/g, and the maximum range is obtainec at a A = 45 degree angle, for which Xmax = V^2/g

Physics
A ballistic pendulum consists of an arm of mass M and length L = 0.52 m. One end of the arm is pivoted so that the arm rotates freely in a vertical plane. Initially, the arm is motionless and hangs vertically from the pivot point. A projectile of the same mass M hits the lower...
