| | You and your team have been up to no good! |
| |
| Your team is traveling across the Pacific Ocean on a tug boat, and you get a call that someone's boat has broken down, leaving them surrounded by great white sharks. You have a catapult with a steel ball (10 kg) loaded in it, and clay balls (20 kg each). The catapult is 8 m long, has a mass of 5 kg, and rotates about its center. The strongest person on your team is able to throw the clay balls at a speed of 47 m/s. Your mission is to save the people on the stranded boat by hitting the sharks in the snout with the steel ball, and to make sure that the sharks recoil with a great enough speed after being hit by the steel ball that they won't want to come back. Better hurry before it's too late and the sharks attack! | After news of the team’s involvement in the boar-tiger apocalypse conspiracy, a warrant has been put out for your arrest. Officers Richard “Big Rich” Hallstein and “Jolly Johannes” Pollanen – notorious for helping cover up the boar-tiger crisis – are put on the case. |

| | In the abandoned garage your team is hiding out in, you discover a vehicle mysteriously labeled “Your GPA”. Unsure of what to make of the name, you decide to just move forward and use the car for your escape. The garage is blocked by a gate which is 7 m across, but luckily for you the vehicle is equipped with a cannon and cannon ball. In order to get the vehicle on the road, you must launch it out from the back of the garage with a spring k<sub>s</sub> = 1.8 x 10<sup>11</sup> N/m and use the cannon ball to open the gate. With the police rapidly approaching your location, you determine the gate has a moment of inertia equal to 50 kg*m<sup>2</sup> and can’t exceed an angular velocity of 10 rad/s. Additionally, in order to escape the police you need to be traveling a minimum of 30 m/s when you exit the garage. |
