An orbiting spacecraft is described not as a "zero-g" but rather as a "microgravity" environment for its occupants and for onboard experiments. Astronauts experience slight lurches due to the motions of equipment and other astronauts and due to venting of materials from the craft. Assume that a 3500 kg spacecraft undergoes an acceleration of 2.60 µg = 2.55 10-5 m/s2 due to a leak from one of its hydraulic control systems. The fluid is known to escape with a speed of 68.0 m/s into the vacuum of space. How much fluid will be lost in 1.00 h if the leak is not stopped?

1. force=massspacecraft*accspacecraft, both given.

but force=massfluidpertime*velocityfluid
solve for massfluidtime (kg/sec)

lost fluid then over 3600 seconds is...
