1 What is the Earth's orbital speed as it orbits the Sun. Take the Earth/Sun distance to be 93 million miles (taking the Earth's orbit to be circular), the mass of the Earth to be 5.97 X 102 kg and the mass of the Sun to be 1.987 X 10*0 kg. Solve this problem using Newton's 2nd law directly 2. A 55.7 kg mass is lifted (at a constant velocity) from the ground to a vertical height of 1275 m....
