You have a rocket with a mass of 2.5kg, that provides a total forward force of F=49N. a.) At what angle must you launch it so that it flies perfectly horizontally. b.) Now you set it up to launch vertically. From rest it takes off but it only has enough fuel to burn for 10 seconds. How high does it get? c.) If it launched at 45 degrees, the fuel burnt for 10 seconds, then it fell to the ground, how far away from its original position would it land?

A two-stage rocket has a total initial mass with the fuel of 4.5x106 kg is docked at rest at a space station. A total of 2.3x106 kg of fuel is on board. The mission for the ship is to reach a planet that is located at a distance of 7.5x1010m away. The fuel is used at a constant rate of 800kg/s for both stages of the rocket. The exhaust velocity for the rocket's engines is 7500m/s (stage1) and 5000m/s (stage2)....
