Q1. The International Space Station orbits the Earth at the average altitude of 362 km. Assume that its orbit is circular, and calculates its orbital speed. The Earth's mass is 5.97×10^24 kg and its radius is 6.38×10^6 m.

Q2. A reconnaissance plane flies 600 km away from its base at 300 km/h, and then flies back to its base at 440 km/h. What is the average speed?

Q3. A car travelling at 37 {rm m/s} runs out of gas while travelling up a 7.0{rm ^ {circ}} slope. How far would it coast before starting to roll back down?
