Amy is very concerned about his weight but seldom does anything about it. After learning about Newton's law of universal gravitation in Physics class, he becomes all concerned about the possible effect of a change in Earth's mass upon his weight. During a (rare) free moment at the lunch table, he speaks up "How would my weight change if the mass of the Earth increased by 10%?" How would you answer Amy?

Asteroid: An asteroid of mass 331 kg orbits the sun in a long-period orbit of 225 years. It is currently at its furthest distance from the sun: 1.11 × 10+13 moving at 184 m/s. m. It is When the asteroid makes its closest approach to the sun – in another 112 years - it will pass within 1.55 x 10+10 m of the sun. How fast will it be going?

1. You and a friend set up an umbrella and chairs at Torrey Pines State Beach. Your friend goes boogie boarding while you read a book. Half an hour later you are surprised to see that your friend has moved south, parallel to the beach. They are still boogie boarding the same distance from shore, in the surf zone. Why did your friend drift parallel to the beach? 2. The Sun is much more massive than the Moon, but the Moon has a bigger influence on Earth's tides than the Sun. Why is this? 3.  Even when there is no wind at the beach, we still see waves. What is the source of these waves? Do not include tides, mass movement, or earthquakes in your answer. 4. What causes ocean surface water to sink to the bottom and become deep water? Where does this happen?  5. How do you escape a Rip Current?

A spaceship moves by Earth at 2.8×108 m/s. A satellite moves by Earth in the opposite direction at 1.3×108 m/s. Use the Galilean transformation to calculate the speed vsatellite,x of the satellite relative to the spaceship. vsatellite,x = ? m/s
