 ====== Project 15: Indiana Jones & The Temple of the Boar Tiger ======
-Indiana Jones is trying to steal a boar tiger idol from another dank cave. Unfortunately for him he has triggered another boulder trap and must escape with his life and the idol. The boulder is sitting on top of a 4.5m incline and the trap is set into motion when a stalactite of mass of 20kg falls moving with a velocity of 31 m/s just before impact onto the 500 kg boulder and embeds perfectly into the boulder setting it in motion. At the bottom of the incline it flattens out so it is perfectly horizontal. Indiana is wearing his rubber shoes and is at the bottom of the incline about to jump onto a vine that is angled 58 degrees from the cave ceiling and reaches to the ground of the incline.  The chasm Indiana needs to get across is 11.3 meters. At the otherside of the chasm is a 1.2 meter concrete platform that then runs into a ton of spikes on the wall. The platform is 7.056 meters below the jumping off point for Indiana Jones. What velocity does Indiana need to jump with and where on the vine should he jump to in order to make it across the chasm and avoid the spikes. Also does the boulder impale on the spikes before or after Indiana makes it across the chasm.
