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.

In this problem you will measure the gravitational constant in a series of “observational experiments,” making use of Newton’s law of gravitation and second law of motion as well as Kepler’s third law of planetary motion a)Newton measured the centripetal acceleration of the moon in its orbit around Earth by comparing the force Earth exerts on the moon with the force Earth exerts on an apple. He obtained a value of ac = 2.66×10-3 m/s2. If Newton had taken the mass of Earth to be ME = 5.95×1024 kg and the mean distance between the centers of Earth and the moon to be RME = 3.86×108 m, what value would he have obtained for the gravitational constant, in units of N⋅m2/kg2?  b)Since measuring the centripetal acceleration of an orbiting body is rather difficult, an alternative approach is to use the body’s rotational period instead. Enter an expression for the gravitational constant, in terms of the distance between Earth and the moon, RME, Earth’s mass,ME, and the moon’s period of rotation…
