On August 10, 1972, a large meteorite skipped across the atmosphere above the western United States and western Canada, much ike a stone skipped across water. The accompanying fireball was so bright that it could be seen in the daytime sky and was brighter han the usual meteorite trail. The meteorite's mass was about 3.8 x 106 kg; it's speed was about 19 km/s. Had it entered the tmosphere vertically, it would have hit Earth's surface with about the same speed. (a) Calculate the meteorite's loss of energy (as a positive number, in joules) that would have been associated with the vertical impact. (b) Express the energy as a multiple of the xplosive energy of 1 megaton of TNT, which is 4.2 x 1015 J. (c) The energy associated with the atomic bomb explosion over Hiroshim. vas equivalent to 13 kilotons of TNT. To how many Hiroshima bombs would the meteorite impact have been equivalent?

Repeat the preceding problem but for a rocket that takes off from a space station, where there is no gravity other than the negligible gravity due to the space station.
The coefficient of friction between the block of mass ml = 3.00 kg and the surface in Figure P7.22 is k = 0.400. The system starts from rest. What is the speed of the ball of mass, m2 = 5.00 kg when it has fallen a distance h = 1.50 m? Figure P7.22
A projectile of mass 2.0 kg is fired in the air at an angle of 40.0 to the horizon at a speed of 50.0 m/s. At the highest point in its flight, the projectile breaks into three parts of mass 1.0 kg, 0.7 kg, and 0.3 kg. The 1.0-kg part falls straight down after breakup with an initial speed of 10.0 m/s, the 0.7-kg part moves in the original forward direction, and the 0.3-kg part goes straight up. Launch a. Find the speeds of the 0.3-kg and 0.7-kg pieces immediately after the break-up. b. How high from the break-up point does the 0.3-kg piece go before coming to rest? c. Where does the 0.7-kg piece land relative to where it was fired from?
You hold a slingshot at arms length, pull the light elastic band back to your chin, and release it to launch a pebble horizontally with speed 200 cm/s.

A bullet of mass 52 grams is fired horizontally into a 5.2 kg wooden block on a horizontalsurface. The coefficient of kinetic friction between the block and the surface is 0.52. Thebullet stops in the block which slides straight ahead for 5.2 meter. At what speed is thebullet fired?(Apply conservation of energy with friction
In a ballaistic pendulum, a bullet of mass m=5.50 g is fired with an initial speed vo=550 m/s at the bob of a pendulum. The bob has mass M=2.00kg and suspended by a rod of negligibel mass. After the collision, the bullet and bob stick together and swing through an arc, eventually gaining a height h. a) please find the h b) please find the kinetic energy of the system before the collison and after the collision (hint: use momentum conservation law for the collision process and then use energy conservation law for the swing process)
There is a large crater in Arizona called Meteor Crater. It is estimated that it was formed about 20,000 years ago by a meteorite that had a mass of about 5 x 10^10 kg and was traveling at a speed of 7.5 km/sec. How fast could this meteorite have hit the Earth (whose mass is 6 x 10^24 kg) if we assume a head-on collision?
