Physics - Jectile II Game

See if you can solve these difficult physics projectile motion problems and see if your answer is correct by shooting a cannon at aliens and alien vehicles. The variables like height, and range are randomly selected so that each problem is different. There are five types of missions or projectile motion problems to solve. You must solve problem 1 before continuing on to problem 2 and so on. As the problems increase in difficulty, so do their point values. You have 10 missions to gather points by solving the five mission problems. The solutions to the five missions are available but you will lose 50% of your point value if you peak. When you get done your 10 mission, you can (hopefully) add your name to the high score list.
