#2, Lecture 6: A spacecraft drifting through the center of a giant cosmic
dust cloud experiences a potential energy that varies with position
as shown (d = distance from the center of the dust cloud). The spacecraft
has a total mechanical energy of E = -4 kJ |
||||||
a) With this energy, what
is the farthest distance the spacecraft could drift from the cloud's center?
(Circle one)
b) Determine the kinetic energy of the craft 2 km from the cloud center. |
