The 2 kg object moving at 5 m/s in the previous problem falls off the edge of a table 1.2 meters above the ground. Determine the total mechanical energy of the object at the time it falls.

Acar travels 40m in 8 seconds find the car speed

What is a costume plot? why is it important to a film or theater production?

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?
