9. Luke is an astronaut that moves his position in the space shuttle by climbing a
3.0 m ladder in 5.0 seconds at Cape Kennedy (g = 9.8 m/s^2). After landing on the
moon (g = 1.6 m/s^2), Luke climbs a 3.0 m ladder in 5.0 seconds to begin the trip back to Earth. Is more power expended by the astronaut on Earth or on the moon, and by what factor?

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m. the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.
