Build a rocket with the right people.You will need… Payload Specialist Thruster Specialist Fuel Expert Structural EngineerBuilding a Rocket on Paper:2.) Calculate total mass of your rocket, must include everything.Total mass = mass of fuel+payload+structure+thrustersBuilding a Rocket on Paper:3.) Calculate the thrust needed to lift your rocket off the launch padNeeded thrust = total mass * gravity F = m * a [Newtons, N]) 1 N =1 kg*m/s21 pound-force = 4.45 Na=gravity=10 m/s2Building a Rocket on Paper:4.) Calculate the total lift (thrust) capability of your rockets thrusters5.) Does your structure support the total weight of the rocket?6.) Do you lift off the ground or did you crash and burn?7.)
