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.

KINEMATICS OF PARTICLE AND RIGID BODIES 1.) A race car accelerates uniformly from 18.5m/sec to 46.1m/sec in 2.47sec. Determine the acceleration of the car and the total distance traveled for the period.

Q2) State whether the following statements are true (T) or false (F). Correct the false statements (answer ten points only) 1. The dynamic means the study of the motion of particles and bodies without taking into account the factors that cause this motion. 2. Calculations in dynamics involve mass and force. 3. The velocity is a scalar quantity. 4. The displacement is a vector quantity. 5. The speedometer in a car measures the speed, which is a vector quantity. 6. A position-time graph is a useful tool for analyzing the friction of bodies. 7. The instantaneous velocity can be calculated graphically from the time-position graph by finding the slope of the line between two points on this graph. 8. The average and instantaneous acceleration can be estimated graphically from the time-position graph. 9. The free-body diagram shows all the internal forces that exerted on an object. 10. Friction acts to resist the motion of the object when two objects are in not contact. 11. The static…
