A 70.0 kg astronaut pushed to the left of a spacecraft with a force F in gravity free space, The spacecraft has a total mass of 1.0 x 10(4)kg. During the push, the astronaut accelerates to the right with an acceleration of 0.36 m/s(2). Determine the magniture of the acceleration of the spacecraft.

A 1500 kg elevator moves upward with constant spped through a veticle distance of 25m. How much work was done by the tension in the elevator cable?
