An object with mass m1 = 9.00 kg is in equilibrium while connected to a horizontal light spring of constant k = 100 N/m that is fastened to a wall. A second object, of mass m2 = 7.00 kg, is slowly pushed up against m1, compressing the spring by the amount A = 0.200 m. The system is then re- leased, and both objects start moving to the right on the frictionless surface. When mị reaches the equilibrium point, m2 loses contact with m1 and moves to the right with speed v. (a) Determine the value of v. (b) How far apart are the objects when the spring is fully stretched for the first time.

Part I. We will leam in this class that the distance from the Earth to the Sun is approximately 1AU = 150,000,000 kilometers. a. Convert this number to meters (1 kilometer = 10° meters) and express it using scientific notation: 150000000000 meters How else might you express this number? (Millions, billions, etc. ?) b. A car on the highway drives at 55 mph = 25 meters per second. How long would it take to drive to the Sun? (Assuming you have a car that works in outer space.) Use the equation distance = velocity x time, or time = distance / velocity. Time = distance/velocity = , seconds (don't forget to use scientific notation.) How many days?. _days How many years?. years Does the answer surprise you?
