One of your summer lunar space camp activities is to launch a 1170 kg rocket from the surface of the Moon. You are a serious
space camper and you launch a serious rocket: it reaches an altitude of 215 km. What gain AU in gravitational potential
energy does the launch accomplish? The mass and radius of the Moon are 7.36 x 1022 kg and 1740 km, respectively.
AU =
-3.63 x108
J
Incorrect
A m 71.2 kg object is released from
rest at a distance h = = 0.746994 R above the
Earth's surface.
The acceleration of gravity is 9.8 m/s².
For the Earth, RE = 6.38 x 106 m, M =
5.98 x 1024 kg. The gravitational acceleration
at the surface of the earth is g = 9.8 m/s².
Find the speed of the object when it strikes
the Earth's surface. Neglect any atmospheric
friction.
Caution: You must take into account that
the gravitational acceleration depends on dis-
tance between the object and the center of the
earth.
Answer in units of m/s.
