Lost in Space AgainContextYou are an engineer at NASA's Johnson Space Center, in charge of assisting astronauts aboard a spacecraft in orbit. You need to program a model to determine how long the ship's two secondary engines need to fire to increase its speed by a certain amount. Constraints The mass of the ship is known.The initial velocity is unknown.The desired speed increase delta V is known.Both motors are similar and exert a known force. They are located on either side of the ship and each generates a force matched to a (known) angle theta to the direction of the ship. Modelization Models the ignition time required for the ship to increase its speed by delta V given the known parameters. Then test your model with the following parameters: Shuttle mass: 1912500 kg; Strength of each motor: 4800000 N; The orientation angle of the motors: 15 degrees; Desired speed increase: 530 km/h.
