Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite is first released from a space shuttle, which is in a circular orbit at an altitude of 185 mi, and is then propelled by an upper-stage booster to its final altitude. As the satellite passes through A, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. The booster is again fired at Bto insert the satellite into a geosynchronous orbit. The second firing increases the speed of the satellite by 4850 ft/s. 29.240 mi 185 mi R-3960 mi Determine the speed of the satellite as it approaches B on the elliptic transfer orbit. (You must provide an answer before moving to the next part.) The speed of the satellite as it approaches Bis ft/s.

The distance from the English Channel Tunnel to Paris is 316.0 km. The train travels at a maximum speed of 300 km/hr except within the English Channel Tunnel, where a 6. (20 pts) Eurostar is a high speed rail service that connects London to Paris. The distance from London to the English Channel Tunnel is 108.0 km. The English Channel Tunnel is 50.5 km long. The distance from the English Channel Tunnel to Paris is 316.0 km. The train travels at a maximum speed of 300 km/hr except within the English Channel Tunnel, where a reduced speed of 160 km/hr is required for safety reasons. a. How long does the journey from London to Paris take? Give you answer in s. b. If the resistance between the train and the track at maximum speed is 120 kN and air resistance adds an additional 20.5 kN (Note: Power = force x velocity), what is the power in horsepower required to power the engine?
