Question:
(a) In the Bohr model of the atom, the ground-state electron in hydrogen has an orbital speed of 2190 km/s. What is its kinetic energy?
(b) If you drop a 1.0-kg weight (about 2 lb) from a height of 1.0 m, how many joules of kinetic energy will it have when it reaches the ground?
(c) Is it reasonable that a 30-kg child could run fast enough to have 100 J of kinetic energy?
