The Tunguska asteroid is estimated to have had a diameter of 50 m, and to have produced an explosion equivalent to 10 megatons of TNT (1 megaton = 4.2 x 1015 joules). Assume that the asteroid was a sphere with density 2 g/cm3. Using the kinetic energy formula K = ½ mv2, where m is the mass and v is the speed, to estimate the speed of the asteroid. Assume that all kinetic energy is converted into the energy of the explosion.
Give your answer in km/s with one significant figure.
If the velocity of the solar wind is about 4.0 ✕ 102 km/s and the visible tail of a comet is 3.0 ✕ 108 km long, how many days does an atom in the solar wind take to travel from the nucleus to the end of the visible tail? (Note: 1 day = 86,400 seconds.)

This spacecraft, appropriately named Stardust, took almost five years to rendezvous with its objective-comet Wild 2 (pronounced "Vilt 2")-and another two years to return its samples. The reason for the long round trip is that the spacecraft had to make three orbits around the Sun, and also an Earth Gravity Assist (EGA) flyby, to increase its speed enough to put it in an orbit appropriate for the encounter.When Stardust finally reached comet Wild 2 on January 2, 2004, it flew within 147 miles of the comet's nucleus, snapping pictures and collecting tiny specks of dust in the glistening coma. The approach speed between the spacecraft and the comet at the encounter was a relatively "slow" 6200 m/s, so that dust particles could be collected safely without destroying the vehicle.

- This is a challenging problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! This problem is closely related to the spectacular impact of the comet Shoemaker-Levy with Jupiter in July 1994. (More information about the event can be found here.) A rock far outside a solar system similar to ours is initially moving very slowly relative to its sun, in the plane of the orbit of a large planet (about the size of Jupiter) around its sun. The rock falls toward the sun, but on its way to the sun it collides with the planet. The mass of the planet is 4 x 1027 kg, the mass of its sun is 3.2 x 1030 kg, the radius of the planet is 1.4 x 10® m, and the center-to-center distance from the planet to the sun is 9.2 x 1011 m.
