An asteroid is moving along a straight line. a force acts along the displacement of the asteroid and slows it down. the asteroid has a mass of 5.2× 104 kg, and the force causes its speed to change from 7000 to 5100m/s. (a) what is the work done by the force? (b) if the asteroid slows down over a distance of 1.4× 106 m determine the magnitude of the force.

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
