Shoot the Monkey Gizmo

I aimed my cannon at 30 degrees with an initial velocity of 20m/s and the monkey successfully caught the banana.

The best technique is to aim the cannon at the monkey and guess and check for the initial velocity.

If the cannon is pointed directly at the monkey at the start of the simulation, then the gravitational pull on both the monkey and the banana will compensate and the monkey will cathch the banana every time.
