A satellite is placed in a circular orbit 300.0 km above Earth’s surface. Earth’s mass is 5.97×10^24 kg and its average radius is 6.38×10^6 m. a. What is the speed of the satellite? b. How many minutes does it take the satellite to complete one orbit?

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
